Attention: This is description for ASAP 2010. The Models are identical.

The ASAP 2010 System consists of an analyzer, a control module, which en­able you to enter analysis and report options, and an interface controller, which controls analyses.

The ASAP 2010 analyzer contains two sample preparation ports and one analysis port. In-line cold traps are located between the vacuum pump and the manifold in both the analysis and the degas system. The sample saturation pressure ( Psat ) tube is located next to the sample analysis port.

The analysis bath fluid Dewar resides on an automatically-operated elevator. Controls and indicators located on a control panel operate the vacuum sys­tems, degas valves, and heating mantles. A sliding shield can be lowered to provide safety or raised to provide access to the sample analysis port and preparation ports.

Gas Requirements

Compressed gases are required for analyses performed by the ASAP 2010 analyzer. Gas bottles or an outIet from a central source should be located near the analyzer.

Appropriate regulators which have been leak checked and specially cleaned are required. Pressure relief valves should be set to no more than 30 psig (200 kPag). Gas regulators are available from Micromeritics; refer to Chap­ter 10, Ordering Information.
