The system incorporates an automatic measuring process, so that several hundred samples can be analysed per day, with unattended operation. When compared to previous versions, the new PAMAS AS3 autosampler has improved reliability, sample preparation, sample handling, flushing and sample diluton.
The system includes a sample preparation probe that breaks all agglomerates in the fluid before analysis. The ultrasonic probe is located on the robot and prepares the subsequent sample whilst the current sample is being analysed. The sample preparation device is cleaned between samples to minimise cross contamination. PAMAS AS3 is equipped with an intelligent flushing device which optimises the sequence of samples. It also has automatic dilution system that adds a programmable amount of solvent online to the raw sample. The system’s inner structural design ensures that the solvent and sample fluid are thoroughly mixed.
