Nondestructive characterization of advanced polymeric materials using spectroscopy and atomic force microscopy |
This joint webinar will focus on polymer materials characterization using the highly complementary techniques of Atomic Force Microscopy (AFM) and vibrational (infrared and Raman) spectroscopy. Infrared and Raman spectroscopy are ideal tools for characterizing unknown materials. The high degree of specificity of spectroscopic analysis makes it ideal for reverse engineering, quality control, defect analysis, and other applications. Infrared and Raman microanalysis is conducted when samples or areas of interest are smaller than approximately the width of a single hair fiber. The spectroscopic microanalysis of polymer based products will be discussed with emphasis on what level of detection can be achieved as well as what is entailed in performing the analysis. Atomic Force Microscopy (AFM) is a powerful technique for mapping topography with resolution down to the atomic level. PeakForce Tapping expands upon traditional AFM by making it radically easier to use while retaining high quality topographic imaging. With PeakForce QNM, PeakForce TUNA and PeakForce KPFM, PeakForce Tapping also enables quantitative nanoscale maps of mechanical and electrical sample properties, at similar resolution to the topographic maps. These capabilities have made PeakFoce Tapping the fastest growing new AFM mode producing hundreds of new publications last year alone. In this webinar we will review a selection of publications highlighting new information obtained by PeakForce Tapping on polymer materials in fields ranging from batteries to organic photovoltaics.

The Use of Raman Spectroscopy in the Pharmaceutical Industry – from Discovery to the Warehouse |
Raman spectroscopy has been utilized in the pharmaceutical community for many years. There are areas of analysis where Raman is in principle the best technique, but many products contain chemicals that exhibit fluorescence precluding its application. For example, Raman should work best for raw material identification, polymorphic studies, high throughput screening, and many others. However, many active ingredients exhibit fluorescence precluding the use of Raman. A new hand-held Raman spectrometer has been developed enabling users to analyze samples, which were previously difficult to impossible to analyze, utilizing new patented fluorescence mitigation methods. The new Raman spectrometer also has a very wide spectra range and high spectral quality thereby optimizing the analysis and resulting in the virtual elimination of false positive/false negative test results for raw material identification.

Greek Yogurt Analysis with the new Multiple Purpose Analyzer for ALL Dairy Applications |
There are two ways to make Greek Yogurt: straining the whey out of the cultured product to make it thicker, or making the milk thicker by ultrafiltration to remove water, or using condensed milk or milk powder to enrich the milk. Typical liquid milk analyzers are only capable of analyzing enriched or ultrafiltration milk samples. They can’t do the cultured milk/strained type of Greek yogurt. With the Multiple Purpose Analyzer – Dairy (MPA-D) Bruker offers a solution for both products: enriched or ultrafiltration milk can go through the liquid sampling module (LSM). The final product is analyzed on the same instrument by reflectance, placing the sample in a glass Petri Dish. Bruker’s Tango (single channel FT-NIR analyzer with touch-screen interface) is an ideal solution where the analysis of the feedstock is in a separate facility, and a dedicated instrument is required for final product analysis. Even Yogurt with added fruit fruits can be analyzed in reflectance with either the Tango or MPA-D FT-NIR systems. With the MPA-D, Bruker Optics has designed a single instrument that analyzes samples from every phase of your manufacturing process: incoming raw materials like raw milk, condensed milk, milk powders, and whey products, in-process testing of vat milk, curds, and cultured milk, and final products, and by-products such as whey, condensed whey and whey derivatives. MPA-D replaces multiple instruments in the Dairy lab, reducing operator training, increasing available bench space, and significantly reducing the total cost of ownership for your Dairy processing operation.

A Fast and Easy Analysis of Complex Samples |
Having optimized the data acquisition, the next step is identifying the unknown compound(s), as well as its distribution, and quantification. Each molecule has a unique spectral signature in the middle infrared region of the spectrum (400-4000 cm-1). This uniqueness makes vibrational spectroscopy highly specific and ideal for identifying unknown compounds. Examples will be presented demonstrating how to utilize infrared spectroscopy and microspectroscopy to identify unknown materials containing one or more compounds. The evaluation of resultant chemical images will also be discussed, to include principle component analysis, component distribution, and quantification.

Sample Preparation - "Then and Now" |
The acquisition of high quality infrared spectra depends on how well the sample is presented for analysis. It can be challenging to acquire optimal data if the sample is small or irregularly shaped. Additionally, if the sample has more than one component, collecting infrared data from isolated areas can be difficult. A review of traditional preparation methods will be presented, as well as a discussion of state-of-the-art methods demonstrating the benefits of employing these methods: time savings and better quality data. This discussion will also include a review of common methods of infrared data collection and which preparation methods are best for each. These methods include transmission, direct reflectance, diffuse reflectance, and attenuated total reflectance (ATR). The optimization of infrared chemical image data collection will also be discussed..

Quick and Easy Quality Control of Polymers using FT-IR |
FT-IR Spectroscopy is one of the fastest and most accurate methods for the analysis and quality control of polymers. High quality IR spectra can be recorded in a few seconds, with little to no sample preparation or additional costs for consumables. Without knowing the chemical composition of the defect, the determination of its origin is often difficult. FT-IR microscopy is an attractive tool for the analysis of contaminations since this technique is capable of identifying not only organic but also inorganic components. The LUMOS has been developed with these types of small samples in mind, along with the intent of providing state-of-the-art microanalysis capabilities with a truly easy-to-use user interface. The LUMOS utilizes a unique objective design, where the numerical aperture is low for optimal sample viewing and high for infrared data collection. This makes it very easy to locate and view the sample without sacrificing infrared performance.

FT-NIR Technology for Process Control in the Food Industry |
The production of any product is a chain of different engineering processes – from the raw materials, over preparing and production steps until the finished product is ready for delivery. Only an error-free progression through each of the single steps guarantees a product of sufficient and constant quality. The analytical control of all raw materials, intermediates and the products is a major issue in all kind of industries. Often classical off-line analysis methods such as HPLC, GC or wet chemistry methods are used. However, this comes with disadvantages; the most significant of these is the high expenditure of time and cost for the analysis. For most, even a laboratory with skilled personal is required.
Quality control during the process
In the Dairy industry the production capacity of plants is still increasing dramatically and therefore the process control becomes more and more important. In addition the quality demands are increasing while the margins are still low. Here the quality is not only important for the customer but even to avoid losses by bad quality batches. There are many applications like
• Monitoring of milk and milk based products in dairy processes, e.g. feed of a spray tower and control of the milk powder on protein, fat, total solids and lactose
• In-line analysis of frying fats
• Control of the fat content in chocolates to guarantee optimal viscosity and fluid behavior during production

Ensure Quality Milk and Dairy Products - From Farm to Refrigerator Using FT-NIR |
The ability to rapidly analyze incoming raw materials, provide timely in-process testing results and final product quality measurements, is imperative to profitable operation in a modern dairy plant. Today, many labs are stuck in an inefficient cycle, employing one instrument to measure protein, fat and solids for incoming milk or whey, another for in-process testing of liquids, slurries and solids and yet another set of tests for the assessment of product quality parameters. Each of these instruments requires some combination of on-going maintenance, chemicals/solvents, and multiple tests performed by a trained technician.
This webinar will introduce a new solution: The Bruker Dairy Analyzer. Lightning fast analysis, based on modern infrared technology and an integrated Liquid Sampling Module (LSM) will dramatically improve your efficiency. The LSM employs automated sampling and homogenization (if required), allowing for streamlined analysis of many dairy products including, but not limited to: Raw, skim, processed and condensed milk, cream, and even ice cream with high total solid and fat concentrations.
