Profile: Analytical Scientific Instruments specializes in analytical testing instruments. Our product line includes primeLine HPLC, PrimeLine syringe, QuickSplit flow splitters, hyperShear mixers, post column reactor modules and PrimeLine replacement parts. Our PrimeLine™ syringe pump, features spring loaded check valves which allow operation in horizontal or vertical mounting position, optical home sensor, micro step drive using R232 PC control, and optional wash seal available for buffer solutions. The model 310 post column reactor (PCR) module can be used to increase detection sensitivity for a variety of compounds including amino acids, proteins, carbohydrates, inorganic ions, and pesticides. The PCR consists of a temperature controller, and a reactor cartridge which is designed to combine efficient mixing with low reaction volumes. This combination provides improved reaction kinetics with less peak dispersion, resulting in maximum detection sensitivity. Our post column reactor features a rupture proof reactor cartridge design, interchangeable cartridge reactor, and digital temperature control panels.
