App Notes

Opiate abuse is drastically on the rise in the United States. In addition to traditional naturally occurring opiates, forensic toxicologists also need the ability to rapidly identify synthetic opioid-like drugs.

In this application note, we evaluate the effectiveness of surface enhanced Raman spectroscopy (SERS) to measure trace levels of imidacloprid, one of a class of insecticides linked to honeybee loss.

Using a photochemical reactor for post column derivatization in combination with the AZURA Analytical HPLC system and Eurospher II C18 column, it was possible to detect ZON, DON and the four aflatoxins B1, B2, G1 and G2 in one chromatographic run.

Bead beating is a very effective and reliable method greatly superior to the manual procedure involving a Vortexer. RETSCH's Mixer Mill MM 400 can be equipped with tube adapters for high throughput, ensuring a reproducible, fast and efficient cell disruption process with very good results.

No sample preparation. No doubts. No headaches. The analysis of Paracetamol is performed using an elution based “TLC – MS interface” coupled with an “expression CMS”. Because of the high matrix tolerance of TLC, very easy sample preparation methods can be applied for suppositories, pain syrup and pills

This application note will show the superior resolving power of the TSKgel UltraSW Aggregate column for the analysis of monoclonal antibody and metalloprotein aggregates formed under forced denatured conditions.

Evaluation of strong and weak cation exchange columns and dependence of separation on mobile phase PH.

Glycosylation is one of the most common forms of post-translational modification of proteins.

In this application note an ADC was analyzed using a TSKgel Butyl-NPR column.

This application describes the use of a 4.6 mm ID × 15 cm TSKgel UP-SW3000 SEC column for fast and accurate mAb aggregate analysis without compromising the quality of the aggregate determination or reproducibility.
