Thermo Fisher Scientific has updated an ion chromatography (IC) method to more easily determine total choline (free and bound forms) in 17 samples representing all forms of infant formula, adult nutritionals, and pediatric formulas (powder, ready-to-feed products, and liquid concentrates).

Thermo Fisher Scientific has developed a simple, efficient, sensitive, and reproducible capillary ion chromatography (IC) method for determining thiosulfate and pyrophosphate in crayfish wash powder.

Thermo Fisher Scientific has developed two rapid and robust high-performance anion-exchange chromatography with pulsed amperometric detection (HPAE-PAD) methods for the accurate determination of common sugars in acid-hydrolyzed wood samples.

Thermo Fisher Scientific has developed a simple, rapid, reliable, and accurate high-performance liquid chromatography (HPLC) method for the simultaneous determination of amlodipine and besylate in an amlodipine besylate drug substance.

Thermo Fisher Scientific has developed a high-performance anion-exchange chromatography with pulsed amperometric detection method, based on AOAC Official Method 2011.18, to determine free and bound myo-inositol in infant formula and adult nutritionals.

This application note from Waters discusses a UPC² method that was successfully developed to separate the three most common carotenoids in less than two minutes.

The UPC²/MS FFA analysis described here provides a simple and fast method with a significant reduction in analysis time compared to alternative techniques such as GC/MS, which requires FAME derivatization.

This application note shows the benefits of quick separation of hydrophobic vitamins and carotenes.
