Application Notes

Mobile phase pH is a powerful tool for separating neutral forms of amines or other organic bases. See how Hamilton used PRP-C18 to separate six basic drug compounds.

A method for determining 16 PAHs in soil matrices using the Extreva Ase system, the Trace 1310 Gas Chromatograph, and the ISQ 7000 single quadrupole mass spectrometer.

This application note demonstrates a quick temperature ramp technique to improve the focusing of VOCs without using a secondary focusing trap.

This application note demonstrates the extraction of 25 PFAS analytes from drinking water using Supelclean™ ENVI-WAX™ SPE as described in regulated method EPA 533.

When detecting and analyzing PFAS, the greatest hurdles lie in the various matrices in which PFAS are found. Custom methods and extensive expertise help to solve these issues.

Learn how the non-targeted analysis of total fluorine can be done using Metrohm combustion ion chromatography.

Although the majority of benzodiazepines metabolize to a single compound, oxazepam, other metabolites can be detected by liquid chromatography.

In this study, a generic, 5-min linear gradient was used to separate six basic drug compounds on a short (50 mm) PRP-C18 column.

The Raffinose Family of Oligosaccharides (RFO) is comprised of low molecular weight non-reducing sugars. Analysis of these compounds is not easily done unless using HC-75.

Paclitaxel originates from the Pacific Yew tree. The isolation of paclitaxel from its major impurities is shown with the use of Hamilton’s PRP-1 (5 µm) HPLC column.

The fast simple method developed by Hamilton Company using the PRP-C18 column allows for simple, efficient identification of the whole vitamin series (K2, K3, and K4).

A Hamilton PRP-C18 (5 μm) HPLC column was used for purification of three oligonucleotides. Analysis of a 21-mer, 22-mer, and 23-mer of similar structure was evaluated.

The new Ascentis® Express PFAS HPLC and delay columns allow the highly efficient separation of 33 PFAS compounds in 5 minutes with reduced background contamination.

The presented methods are suitable for the quantification of THC and THCA (and other cannabinoids) in Cannabis sativa and to check THC-free cannabis for compliance.

This application note introduces a simple targeted extraction method for the analysis of nine nitazene compounds from urine and blood using the Clean Screen® DAU column.

The primary nucleosides encompass a broad array of biological functions associated with RNA, particularly after configuration into multidimensional conformations.
