PAS-II autosampler


Product details


Product Features 
PAS-II auto sampler is a new type of automatic control, independent work, and unattended automation equipment. Users can be based on different needs matching different types of ion chromatography; The device is easy to operate, with LCD touch screen in a human-computer interaction manner, using the RS485 serial communication interface with a computer connected or can be connected directly to the chromatograph; PAS-II auto sampler electric injection valves employ full tubular injection method, a high degree of accuracy and repeatability; direct Trace sample injection and rapid analysis, effective solution to the injection residues, injection speed and injection reproducibility and other issues; The device is able to adopt a variety of samples, user-selectable injection volume, the amount of cleaning and their analysis times. Higher working efficiency and accuracy.
