These functions make it less flexible, trusted, consistent, and affordable than the Centurion WS. Their gradual hot water wash with a needle also offers less carryover protection. The Centurian WS achieves high production due to its twin concentrator style for water and earth samples, and its nice taste placing of 100 water samples and 90 earth samples.

The Archon/OI Model 4552 does not possess these features.
An autosampler for purge and trap is an essential investment for independent analysts and laboratories that analyze solids and liquids using the GC/MC process. Although many laboratories use the Archon/OI Product 4552, it doesn’t offer the same analytic superiority, technical robustness, production, ease of use, and ease of maintenance because the Centurion WS. For large labs and independent analysts whose funding depends on study cost and quality, the Centurion WS the most effective autosampler for purge and trap.
Autosamplers are essential for labs that process a high volume of samples utilizing a fuel and/or fluid chromatograph. Letting an autosampler to inject products right into a chromatograph effects in larger trial consistency and a more efficient chromatography method compared to injecting the samples by hand. For these factors, many laboratories pick for autosamplers in place of stand-alone concentrators that require information assistance.
