Comparing the Centurion WS to the Archon/OI Model 4552 should be done using criteria that establish the overall price of an autosampler to the user. These criteria are: The Centurion WS features digital, three-position supply, a programmable 1ul-100ul supply, and does not require priming. These characteristics give it one of the very adaptable, reliable, consistent, and economical IS/Surr distribution programs on the market. By using a rapidly hot water rinse in a set volume loop that keeps water in the pathway warm, and flushing the minimizer parameter soil hook and transfer point with P&T’s Bake fuel, additionally, it functions excellent carryover reduction.

The Archon/OI Design 4552 characteristics technical, two-position distribution, a 1ul distribution, and needs priming. These characteristics ensure it is less flexible, trusted, consistent, and affordable compared to the Centurion WS. Their slow heated water wash with a syringe also presents less carryover protection. The Centurian WS defines high output because of its combined concentrator setting for fluid and earth products, and its generous trial positioning of 100 water samples and 90 land samples. These characteristics produce cost savings for the GC/MC process and increase untreated autosampler operation. The Archon/OI Product 4552 lacks a double concentrator setting and only features positioning for 51 samples.

Offering handheld remote control and intuitive Windows XP Application that is exhibited on a 15″ wise monitor, the Centurion WS is one of many easiest knauer autosampler to use. In comparison, the Archon/OI Model 4552 can not be managed remotely, and functions a screen that’s manipulated via a little keypad. The Centurion WS offers three features that make it simple to steadfastly keep up: an error tracking and taste log, on-board real-time movement diagrams, and complete on-board diagnostic checks. The Archon/OI Design 4552 doesn’t possess these features.

An autosampler for purge and trap is an important expense for separate scientists and labs that analyze solids and drinks using the GC/MC process. Although a lot of labs utilize the Archon/OI Product 4552, it generally does not provide exactly the same analytical superiority, physical robustness, productivity, ease of use, and simple maintenance whilst the Centurion WS. For large labs and independent researchers whose funding is dependent upon study price and quality, the Centurion WS the very best autosampler for purge and trap.

An autosampler automates the water trying method by functioning on a programmed time schedule, or in terms of conditions which are translated by sensors. In either case, autosamplers improve the efficiency of gas chromatography (GC) trying – a procedure by which inlets were once stuffed by hand. Nowadays, researchers can decide between many makes and types of autosamplers, of which the Cobra L/S liquid sampler is one of many best. Featuring a simple, light style and easy operating procedures, that autosampler presents the following benefits, among others:

The equipment’s all-electric style allows labs to cut back operating charges by reducing the need to purchase a carrier gasoline for the cellular phase. For big labs and features which contain numerous labs, this can develop meaningful savings. Some autosamplers have a small selection of injection and syringe load prices, nevertheless the Cobra autosampler has a selection that accommodates that most demanding process requirements. Regardless of GC choosing method you apply, this autosampler may match their shot / syringe fill needs. Preferably, an autosampler must use off-the-shelf syringes and not private ones. In addition to charging a lot more than off-the-shelf syringes, amazing syringes are difficult to supply on a crisis basis.
