Once they select an autosampler for purge and lure, several laboratories thin their possibilities to the Centurion WS Autosampler and the Archon/OI Design 4552 Autosampler. If you should be analyzing these autosamplers, the reviews under may aid your evaluation.
The Centurion WS features electric, three-position distribution, a programmable 1ul-100ul distribution, and does not need priming. These features give it one of the very most versatile, trusted, regular, and economical IS/Surr delivery systems on the market. By using a rapidly warm water wash in a set size hook that keeps water in the pathway warm, and flushing the minimizer parameter earth needle and move range with P&T’s Cook gas, in addition, it features exceptional carryover reduction.
The Archon/OI Model 4552 features physical, two-position supply, a 1ul delivery, and requires priming. These characteristics allow it to be less flexible, trusted, regular, and affordable compared to Centurion WS. Its gradual heated water wash with a needle also presents less carryover protection. The Centurian WS defines high production because twin concentrator style for liquid and soil products, and their large trial positioning of 100 water products and 90 earth samples. These characteristics create charge savings for the GC/MC method and improve untreated varian autosampler operation. The Archon/OI Design 4552 lacks a double concentrator setting and just characteristics positioning for 51 samples.
Featuring remote control and user-friendly Windows XP Application that’s displayed on a 15″ smart monitor, the Centurion WS is among the easiest autosamplers to use. In comparison, the Archon/OI Product 4552 can’t be managed remotely, and characteristics a screen that is altered with a small keypad. The Centurion WS offers three characteristics that make it easy to keep: one tracking and taste log, on-board real-time flow diagrams, and total on-board diagnostic checks. The Archon/OI Product 4552 does not possess these features.
An autosampler for purge and trap is a significant expense for independent researchers and labs that analyze shades and beverages utilizing the GC/MC process. Although a lot of labs utilize the Archon/OI Product 4552, it doesn’t present the exact same logical superiority, physical robustness, output, ease of use, and ease of preservation while the Centurion WS. For big laboratories and independent researchers whose funding depends on research cost and quality, the Centurion WS the most effective autosampler for purge and trap.
Autosamplers are necessary for labs that method a high level of products employing a gas and/or water chromatograph. Allowing an autosampler to insert products into a chromatograph results in higher sample reliability and a more efficient chromatography method compared to injecting the samples by hand. For these causes, most laboratories pick for autosamplers in place of stand-alone concentrators that require manual assistance.
Due to its refined technology, an autosampler can be quite a significant investment. Consequently, many labs, especially those opening or growing on a restricted equipment budget, opt to get them used. If you’re considering investing in a pre-owned purge and capture autosampler, the ideas below will allow you to find one that gives quality performance for an acceptable price:
Two things determine the longevity of a pre-owned equipment: how properly it’s been preserved, and how well it’s designed. Concerning the latter, be sure you pick a design that gets stable reviews. Efficiency areas to keep yourself updated of as you investigate opinions are: analytic ability, physical reliability, production, easy preservation, and simple use.
A poorly preserved autosampler may breakdown prematurely and crash to provide exact readings. The simplest way in order to avoid getting laxly maintained purge and capture gear is to request a maintenance report for every single autosampler you consider buying, actually types that have received small use.
