App Notes

Unlike low-tech carbon black and activated carbon, specialty carbon adsorbents are engineered materials, manufactured from highly pure synthetic polymers.

This application note shows the complete United States pharmacopoeia monograph method for Aripiprazole.

This Application Note demonstrates the fast and non-destructive handheld Raman spectroscopic identification of polymers – including ABS, PE, PS, PET, and PMMA – of different colors after building a suitable library.

TPH (C6-C44) analysis is a time consuming exercise with numerous sources of errors. The JSB GCxGC solution minimises the sample preparation and data manipulation steps, providing accurate results and maximises your return on investment.

Method Transfer LC-UV to LC-MS

This application note looks at the use of nitrogen for both vial pressurisation and GC carrier gas.

Fortification of milk, dairy products, infant and adult nutritionals with vitamin D is required in many countries to provide additional dietary vitamin D.

Polydextrose is a low-calorie synthetic polymer of glucose. It is an accepted additive for food. In the application presented, polydextrose is determined in biscuits by anion-exchange chromatography followed by pulsed amperometric detection (PAD) in accordance with AOAC 2000.11.

This application note describes a complete untargeted metabolomics workflow using a Thermo Scientific™ Orbitrap™ MS-based GC to detect biomarkers for time of death in a rat model.

In this application we show sample prep-free quantification and identification of caffeine in energy drinks by elution-based coupling of Thin Layer Chromatography with Mass Spectrometry.
