As mentioned in our email to you regarding new opportunities for NMR especially for 600 MHz users, we want to give more details.

As you probably are aware, Human metabolomics has seen a rapid rise in the world of Omics and currently is a major source of funding in many countries worldwide. NMR is one of the 2 main tools in Metabolomics, highly synergistic to mass spectrometry, which is the other tool in use.

At Bruker we have developed a standardized approach to generate high quality spectra of human bodyfluids and analysis of the spectra in terms of quantification from the mixture spectra and also statistical analysis. This is all centered on our IVDr platform and covers currently Urine, Plasma, Serum, CSF and Methanol extracts (from bodyfluids, tissues, cells).

As you can see from below, the complete solution is consisting of 4 levels. Level 1 and 2 are requirements to use the enabling tools and assays in level 3 and 4. In level 4 the grey and yellow boxes describe collaborative developments with partners currently in progress. Everything listed in the blue boxes is available for ordering. Detailed descriptions of all enabling tools can be seen on the tabs below.

IVDr Bild1

We have a base of more than 75 users worldwide working with our standards already and such creating exchangeable spectra for large scale epidemiology research or clinical trials. Amongst those users are also hospitals, biobanks and the members of the International Phenome Center Network (IPCN).

In case you are interested yourself in entering this field, we can inform you, what would be needed to progress to the IVDr platform standard. Since shared use with other applications will be a need for such upgraded systems, we want to assure you, that you are not losing the shared capabilities of the instrument. The IVDr system itself is a fully functional NMR spectrometer, if your system has 3 or more channels, no problem, we can also adapt an existing TCI cryoprobe, even so our first choice are 5mm inverse probes e.g. BBI or TXI.  This however is related to minimum down time for probe exchange and ease of use. In hospitals we want a MTA to be able to run the system in daily routine and avoid non-availability of the systems due to regular warm up procedures as needed on CryoProbes. In addition it should be mentioned, that the sensitivity gain using a cryoprobe for the typical bodyfluid screening experiments is at maximum a factor of 1.6 due to the high salt content.

Upgrade Your Console

We also want to point out, that we already had discussions with several users, where a medical or clinical/translational research department or biobank is in the same organization and was interested to get access to NMR based metabolomics. Such a source of income could be opened to the NMR owners and access to high ranking publications assured. We can support you in identifying potential partners in the human metabolomics field in your environment.

Below you can see typical use cases of the IVDr platform in the clinical/translational value chain.

Level 2 - Bruker IVDr Methods: B.I.Methods 2.0

As you are surely aware, there is a strong need for standardization, guaranteeing highest spectral performance, reproducibility and transferability of routines used. This defines, what our   level 2, the B.I.Methods 2.0 has to ensure. The following features are integral part of the procedures


  • Advice on sample collection, storage and transfer to magnet
  • SOP for sample preparation for 3 and 5mm tubes


Spectral properties

  • Generated under fully automated data acquisition and processing conditions
  • Flat baseline without any offset
  • High quality signal suppression for water and methanol at low presaturation power
  • 90 degree pulse and presaturation power are adjusted for every sample, the latter making sure, if integral correction factors are need for signals close to solvent lines being suppressed, they are always the same
  • Automatic transfer of optimized parameters to the 2D-Jres experiment done on every sample
  • Residual solvent signals are always in phase with all non-suppressed signals
  • Automatic phase correction works without errors
  • Daily QC samples to ensure integral calibration, absolute temperature and solvent suppression are correct and integral value for 1 proton is stored in the dataset
  • QC reports for every sample

Based on the spectra obtained with B.I.Methods 2.0 (available on Avance III HD or Avance Neo with Windows Operating System), the following enablings Tools (Layer 3) can be applied

As you can imagine, such routines can also be of importance for best performance in other applications you run in Water or Methanol. So you can multiply benefit here.

Level 3 – Bruker IVDr BioBank Tool: B.I.BIOBANK-TOOL

NMR analysis is a sensitive and specific tool for biobank QC. As it is also completely standardized, it strongly supports the high need for standardization in biobanks. A biobank should only contain high quality specimens to justify the storage cost. It is vital to be able to have as much information on each aliquot as possible to avoid any wrong conclusions in biobank based clinical trials or research studies. The IVDr Biobank tool generates 36 parameters e.g. for urine QC, it checks for wrong labeling of samples, for unreported drug treatment, high protein content in the urine and  fasted or non-fasted state, just to mention a few.

In addition to the QC part, NMR can deliver added value for the biobanks. Whenever a QC test is done through the IVDr platform, a spectrum is available, that can also be transferred to the biobank metadata. Having spectra allows to run the quantification tools ( B.I.LISA and B.I.QUANT-PS 2.0 for plasma/serum and B.I.QUANT-UR for urine) and the results thereof can be added to the biobank as well. The potential of this can be imagined easily, when multiple biobanks work along the IVDr SOPs and store spectra and quantification results, as these data are completely standardized and can be exchanged with other biobanks worldwide.

An overview of IVDr based biobanking solutions is given below

Quantification results are available as follows and can be ordered as package together with the B.I.Biobank-Tool


  • B.I.LISA lipoprotein parameters including subclass information
  • B.I.QUANT-PS Small molecule quantification


  • B.I.QUANT-UR basic 50 small molecule endogenous metabolites
  • B.I.QUANT-UR extended 150 small molecules endogenous + disease markers (children + adults)
  • B.I.QUANT-UR neonate extended 150 small molecules endogenous + disease markers (newborns) + non-targeted statistical classification result compared to healthy newborn model

Level 3 - Bruker IVDr Lipoprotein Subclass Analysis: B.I.LISA

Lipoprotein distributions play a major role in cardiovascular risk assessment, while the main fractions

  • HDL = High Density Lipoprotein
  • IDL  = Intermediate Density Lipoprotein
  • LDL = Low Density Lipoprotein
  • VLDL = Very low Density Lipoprotein

And the typical house doctor`s panel

  • Total Cholesterol
  • Total Triglyceride
  • LDL Cholesterol
  • HDL Cholesterol

can be readily obtained by conventional analysis, subfractions of LDL, HDL and VLDL is best measured by NMR. In the Literature various publications show, that subfractions, especially LDL and HDL cholesterol, can produce better risk analysis, they are also carry information in various types of cancer.

B.I.LISA produces 115 parameters, including e.g. Particle numbers, APO A1, APO B and APO A2, cholesterol, free cholesterol, triglyceride and phospholipid main and subfraction values. The values are obtained by NMR regression training on ultracentrifugation results of a representative human cohort. Ultracentrifugation is considered the gold standard in the subclass analysis, however the total analysis time is about 1 week, while NMR does this in 10 minutes.

Below you can see a typical healthy panel (left side) to a panel obtained from a subject, that had a severe stroke 3 days after sample collection. The grey bars indicate the reference range in the cohort used to build the regression model. The black horizontal bar shows the person under test for all parameters.

With exactly the same experiment done for lipoproteins, also small molecules in plasma and serum can be quantified using our B.I.QUANT-PS 2.0 tool.

Level 3 – Bruker IVDr Quantification in Plasma/Serum: B.I.QUANT-PS 2.0 new

With Version 2.0 41 Metabolites are quantified under full automation from serum and plasma. For each metabolite the reference range as obtained from NMR is shown again with grey bars, the black bar shows the person`s values superimposed. In order to improve our quantification results, we have now introduced the raw concentration (r), which can also be below LOD. TMAO and branched chain amino acids are known to contribute to the risk of cardiovascular disease as well. So with B.I.LISA and B.I.QUANT-PS we offer 2 viewpoints with one experiment and further improved cardio risk analysis is obtained.

An extract showing 1 page of the quantification report including the Aminoacid part of the quantification is displayed below. In case of doubt, an interactive plot can be obtained showing the real spectrum versus the fit.

All Metabolites have undergone wet spiking according to DIN-ISO norm.

Level 4 – Bruker IVDr Inborn Error of Metabolism Panel: B.I.IEM Panel

For the 2 extended versions, B.I.IEM-Panel new can be applied on the quantification list. If added as part of the analysis process, the quantification results are transferred automatically to the Bruker version of the Metagene knowledge base, which covers more than 1000 rare diseases and is constantly updated. The output of Metagene to the user consists of a ranked list of diseases, that can be explained by the metabolites identified in outlying concentration ranges. In addition to the disease, the markers and their expected concentrations as well as the clinical symptoms are listed. With this additional automatic step a new level of intelligent analysis is offered.
