PAMAS AS3

PAMAS AS3

Autosampler for fully automated Oil Contamination Analysis

The fully automated PAMAS AS3 autosampling system analyses high quantities of samples. This new system is designed to provide sample analysis of several hundred samples per day, with unattended operation. The system offers a multitude of features regarding sample preparation, sample handling, flushing and sample dilution. 

Sample preparation: The PAMAS AS3 system includes a sample preparation probe that breaks all agglomerates in the fluid before analysis. The ultrasonic probe prepares the subsequent sample whilst the current sample is being analysed. The sample preparation device is cleaned between samples to minimise cross contamination.

Sample handling: The new system has a XYZ stage, operating with samples on trays as these are the most widely used method in high quantity laboratories. RFID (Radio Frequency Identification) or barcode systems can be used optionally to automatically identify the trays. The system is servo motor driven. This increases the speed of operation and reduces the noise level below that of stepper motors.

Seamless integration to LIM system: The system can be linked to an existing LIM (Laboratory Information Management) system. If the existing LIM system can forward sample IDs based on tray number and x/y position within the tray, no individual sample identification procedure is necessary. If the samples carry RFID or barcode labels, samples can be identified with an attached reader (optional). A close link to the LIM system helps to request information about samples. It is possible to transfer special condition options for samples using the LIM system.

Flushing: The PAMAS AS3 autosampling system is equipped with an intelligent flushing device which optimizes the sequence of samples

Sample dilution: Some samples may either be too dirty or too viscous or may contain undissolved additives or undissolved water. In this case, sample dilution with low viscous solvents helps to get reliable measuring results. The new system has an automatic dilution system that adds a programmable amount of solvent online to the raw sample.
