Main features of the amino acid reaction module:

• Programmable heating column thermostat (with Peltier elements): +20 - +99 °C, with active cooling option and solvent leakage sensor.
• Temperature-controlled pre-column derivatization reactor for ninhydrin reactions, ambient temp. - up to +180°C. Automatic washing/rinsing cycle after each analysis to avoid clogging. Due to his special training, the efficiency of derivative formation is practically 100%.
• Built-in reagent dosing pump (0.1-2 ml/min)
• Built-in 2-channel photometer, maintenance-free, wavelength: 570 nm and 440 nm

Quaternary gradient pump

It has an analytical size range for the delivery of eluents (0.01 – 10 ml/min, max. 400 bar). Specially designed two-piston pump for low pulsation. Among other things, the gradient profile can be seen on the graphic display. Programmable mixing cycles and rinses. Liquids are degassed in the built-in 4-channel vacuum chamber

Automatic sample feeder

With a large graphic display and keyboard, in which 120 sample containers can be placed on the refrigerated trays. Dosable volume: adjustable from 1-100 µl in 1 µl increments. Programmable temperature (5 – 70 °C), sample sequence and washing procedure. It can also be used as a conventional HPLC sample dispenser. Optional: pre-column derivatization. With the help of a programmable washing program, the entire injector system can be rinsed, in order to avoid cross-contamination of the samples.

Inert gas, cooled reagent grader

The buffers can be placed in 500 ml or 1 liter bottles in the Peltier cell-cooled storage. The solutions are stored in an inert gas (N2) atmosphere to avoid oxidation and contamination. Liquid level prediction of solutions.

Device control, evaluation

The device is computer controlled. Hardware control, data collection and evaluation are performed by the Clarity software. The software is user-friendly and easy to learn. The software is FDA-21 CFR Part 11 compliant.
