AB806: Automated Solid Phase Extraction (SPE) of Nitrosamines in Water

Instrument Type: Automated Sample Prep

Due to the carcinogenic nature of nitrosamines at very low levels, new regulations setting detection limits at PPT (ng/L) levels have been set for nitrosamines in drinking water, milk, beer, and food products. EPA Method 521 recommends coconut carbon SPE cartridges and this method can be easily adapted for the analysis of food and beverages.

Simple isocratic analysis of gun powder residue

Instrument Type: HPLC

The Thermo Scientific HPLC system is applied for the analysis of gun surveillance standards. The separation is performed on a Thermo Scientific Acclaim Explosives E2 column, with UV detection at 254 nm.
