VIP-HESI
VIP-HESI (Vacuum Insulated Probe Heated Electrospray Ionization) is a cutting-edge ion source designed to enhance sensitivity and optimize mass spectrometry (MS) analytical tasks. With its heated electrospray technology, VIP-HESI significantly increases ion yield, surpassing the capabilities of standard electrospray. This leads to a substantial gain in sensitivity for a wide range of compounds, making it an invaluable tool in metabolomics and pharmaceutical analysis, environmental analysis, food testing, and forensic drug investigations. With a proven track record as a robust workhorse ion source on Bruker Triple Quad mass spectrometers for nearly a decade, VIP-HESI has become an industry favorite.
One of the significant advantages of VIP-HESI is its compatibility with a wide range of instruments. The latest version can be used with all timsTOF and QTOF (Quadrupole Time of Flight) series instruments and can be quickly and easily installed. Leveraging its advanced features, VIP-HESI achieves sensitivities comparable to those of leading Triple Quad MS for diverse compounds. Furthermore, it retains the advantages of accurate mass values with TIP (True Isotopic Pattern). Operating the VIP-HESI is straightforward, thanks to its simple parameters, and it includes an efficient active exhaust system, enabling seamless upgrades from conventional sources.
The enhanced performance, the VIP-HESI system offers the microFlow emitter as an optional addition to its standard ESI sprayer. This simple drop-in replacement boasts an inner diameter of 50 µm, significantly improving peak intensities within the lower flow range limits of the VIP-HESI source (ranging from 1 µL/min to 50 µL/min). The microFlow Emitter's narrow ID is the ideal solution for achieving increased analytical depth while maintaining robustness.
VIP-HESI is a dual-source system that combines VIP Heated Electrospray with Atmospheric Pressure Chemical Ionization (APCI) probes as standard. This powerful combination ensures versatile capabilities and allows researchers to explore a wider range of applications. By incorporating VIP-HESI into their analytical workflows, scientists can unlock new possibilities and achieve remarkable results.
Technical Details
The ion source significantly improves sensitivity and reduces detection limits by enhancing ionization efficiency across a wide range of applications. In the VIP-HESI system, an electrospray is maintained at a precisely controlled vaporizing temperature. This enables the analyte ions to undergo enhanced desolvation, even at high eluent flow rates during UHPLC separations, resulting in sharp chromatographic peaks.
Within the Vacuum Insulated Probe (VIP), the eluent stream containing the compounds of interest is effectively shielded against heat by a vacuum barrier, similar to a dewar. This combination of heating and integrating the eluent stream into the probe results in a simple and easy-to-maintain design. Additionally, the implementation of a powerful active exhaust, utilizing the Venturi effect, effectively prevents re-circulation. This demonstrates a smart application of well-established physical principles in modern instrumentation.
Applications
VIP-HESI in Forensics
Ethyl-Glucuronids (EtG and EtS) are markers for alcohol misuse. The VIP-HESI source yields great sensitivity for determination of EtG from blood. For details, please refer to application note LCMS-122.
VIP-HESI in Food Safety
Extremely sensitive analytical methods are required for accurate low-level identification, and quantitation of zero-tolerance compounds in food.
Bruker’s TargetScreener application is boosted more than 10-fold for a representative subset of analytes when used with VIP-HESI instead of regular ESI source.
The VIP-HESI achieves a Limit of Quantitation (LOQ) more than 100 times lower than the minimum required performance level (MRPL).
VIP HESI in Glycopeptide Determination
Glycosylation is a common critical quality attribute (CQA) of therapeutic proteins and needs to be characterized during product development. Typically, this analysis is conducted after enzymatic release and tagging of the glycans followed by fluorescence and MS detection. A more modern workflow is to identify glycan compositions directly from tryptic peptide maps acquired with the timsTOF Pro and PASEF® in combination with analytical LC and the new VIP-HESI ion source. It employs a glycan search method from peptide mapping data and uses previously identified aglycons as mass tags.
APCI II
Atmospheric pressure chemical ionization (APCI) is used for less polar molecules where ESI fails to deliver reasonable quantities of ions. In contrast to ESI, it produces mainly singly-charged ions even for larger molecules.
APCI is only limited in the case of thermally unstable compounds, since evaporation of the solvent is done by heating the sample in the nebulizer needle. APCI is often used for metabolomics as well as for drug or pesticide screening.
The new Bruker APCI II source is of course compatible to Bruker's unique DirectProbe option DIP. The direct injection probe is a novel smart solid sample introduction technique allowing a rapid analysis of solids. Sample preparation is as simple as dipping a disposable glass capillary into the solid sample.
APPI II
Atmospheric pressure photo ionization (APPI) is used for less polar or non-polar molecules that can not be ionized in either ESI or APCI.
APPI delivers a wide dynamic range and low chemical noise. With an operational flow range of 2 µl/min – 1500 µL/min it is compatible with cap- to analytical chromatography.
APPI II by Bruker Daltonics is the only APPI source with DirectProbe option for direct analysis of solid samples. The direct injection probe is a novel smart solid sample introduction technique allowing a rapid analysis of solids.
Sample preparation is as simple as dipping a disposable glass capillary into the solid sample.
