Once they choose an autosampler for purge and lure, several labs thin their choices to the Centurion WS Autosampler and the Archon/OI Design 4552 Autosampler. If you are evaluating these autosamplers, the reviews under will support your evaluation.

Comparing the Centurion WS to the Archon/OI Product 4552 must be done applying standards that establish the general price of an autosampler to the user. These standards are: The Centurion WS characteristics electric, three-position distribution, a programmable 1ul-100ul supply, and does not require priming. These features give it one of the very most flexible, trusted, consistent, and economical IS/Surr delivery systems on the market. With a quickly warm water wash in a fixed size loop that maintains water in the pathway warm, and flushing the minimizer parameter earth needle and transfer range with P&T’s Cook gas, additionally, it characteristics outstanding carryover reduction.

The Archon/OI Model 4552 functions technical, two-position supply, a 1ul supply, and involves priming. These characteristics make it less adaptable, reliable, consistent, and cost effective compared to Centurion WS. Its gradual warm water rinse with a needle also offers less carryover protection. The Centurian WS achieves high productivity because combined concentrator function for liquid and soil products, and its large test positioning of 100 water samples and 90 soil samples. These functions produce charge savings for the GC/MC process and raise unattended autosampler operation. The Archon/OI Model 4552 lacks a twin concentrator style and only characteristics positioning for 51 samples.

Offering handy remote control and user-friendly Windows XP Computer software that is exhibited on a 15″ clever check, the Centurion WS is one of many easiest autosamplers to use. On the other hand, the Archon/OI Design 4552 can’t be managed remotely, and functions a screen that’s manipulated using a little keypad. The Centurion WS offers three characteristics which make it easy to keep up: an error tracking and taste wood, on-board real-time movement images, and total on-board diagnostic checks. The Archon/OI Product 4552 does not get these features.

An autosampler for purge and lure is an important investment for separate analysts and labs that analyze solids and drinks utilizing the GC/MC process. Although some laboratories utilize the Archon/OI Design 4552, it generally does not provide exactly the same systematic superiority, technical robustness, output, simplicity of use, and simple preservation as the Centurion WS. For large labs and independent researchers whose funding is dependent upon research price and quality, the Centurion WS the most effective autosampler for purge and trap.

An autosampler automates the liquid testing process by functioning on a programmed time schedule, or with regards to situations that are saw by sensors. Either way, autosamplers improve the efficiency of gasoline chromatography (GC) testing – an activity by which inlets were after filled by hand. Nowadays, researchers can decide between several makes and types of autosamplers, of which the Cobra L/S water sampler is one of many best. Presenting an easy, lightweight design and easy running techniques, this autosampler presents the next benefits, among others autocampionatore spazio di testa:

The equipment’s all-electric design allows laboratories to reduce operating costs by eliminating the requirement to purchase a carrier gasoline for the cellular phase. For large laboratories and services that have multiple labs, this will produce significant savings. Some autosamplers have a limited selection of procedure and syringe load rates, however the Cobra autosampler includes a range that accommodates that most demanding process requirements. Regardless of the GC testing method you apply, that autosampler may meet its injection / syringe load needs.
