 The MASTER AS Liquid Autosampler, a robotic X-Y-Z coordinate sampling system, delivers superior flexibility, repeatability, and performance to increase sample throughput and meet each laboratory’s changing workload.
 The extremely flexible MASTER AS features three separate and removable 2-mL vial racks for a total capacity of 160 samples. 


Furthermore, 10-mL and 20-mL vial racks are also available for a capacity of 65 samples. The autosampler has a capacity for up to five 10-mL solvent vials and up to five 10-mL waste vials, eliminating carry-over and presenting numerous solvent possibilities. 

Additionally, the sample trays are far from the GC oven, preventing possible sample degradation and solvent evaporation caused by heat exposure.

 All injection parameters can be optimized according to the laboratory's needs, the sample type, and the application. The MASTER AS allows the utilization of up to seven different syringe capacity types ranging from 5 μL to 500 μL, offering a great choice of injection volumes from 0.1 μL to 500 μL. 

The syringe can be easily exchanged by using the Syringe Replacement function, which brings the Y axis of the MASTER AS to a handy position.
 

The capacity to provide the most flexible, accurate, automated headspace system comes from a rich and long tradition in innovation. The culture of innovation is a legacy carried over more then three decades of real and proven experience in Headspace sample handling. 

This is the background that originated the new Master SHS Static Headspace Sampler. Static Headspace sampling technique is the most commonly used technique for the analysis of volatile and semivolatile compounds. The new Master SHS is a very flexible system and can be applied to the most widely differing sampling matrices.
For laboratories pursuing highly reliable results, the most appropriate solution is a tough, robust and precise sampling system able to provide straightforward results for virtually any analytical need.  

Master SHS delivers the highest performances to overcome daily new challenges and supplies trustworthy and enhanced results.


SAMPLE HANDLING: 120 position vial tray, maximum compatibility, unlimited priority sample position, unmatched oven capacity, vial shaking function, leak check automatic procedure. Positive recognition for quality control.


Among its benefits: 

limited or no sampling preparation, 
no contamination risk, 
reduced danger of false results, 
diminished inlet or column maintenance, outstanding sensitivity, 
completely automated analysis, 
easy to use,
 highest sample throughput, 
absence of artifact or sample degradation, robust and trouble-free design.
