Choosing a Purge and Trap Autosampler


Once they pick an autosampler for purge and trap, many labs slim their choices to the Centurion WS Autosampler and the Archon/OI Product 4552 Autosampler. If you should be analyzing these automuestreado, the comparisons under will assistance your evaluation.

Researching the Centurion WS to the Archon/OI Design 4552 should be achieved using requirements that establish the general value of an autosampler to the user. These standards are: The Centurion WS functions electric, three-position supply, a programmable 1ul-100ul distribution, and doesn’t involve priming. These functions give it one of the most versatile, reliable, regular, and economical IS/Surr supply programs on the market. Using a rapidly warm water rinse in a fixed volume trap that maintains water in the pathway warm, and eliminating the minimizer parameter land needle and transfer line with P&T’s Cook fuel, in addition, it features exceptional carryover reduction.

The Archon/OI Design 4552 functions technical, two-position supply, a 1ul supply, and requires priming. These features allow it to be less flexible, reliable, regular, and cost effective than the Centurion WS. Their slow warm water wash with a needle also presents less carryover protection. The Centurian WS achieves large production because dual concentrator function for water and soil samples, and its nice taste positioning of 100 water samples and 90 land samples. These functions create charge savings for the GC/MC process and raise unattended autosampler operation. The Archon/OI Model 4552 lacks a twin concentrator mode and only features positioning for 51 samples.

Offering remote control and spontaneous Windows XP Pc software that’s exhibited on a 15″ intelligent monitor, the Centurion WS is one of the best autosamplers to use. On the other hand, the Archon/OI Product 4552 can’t be controlled slightly, and functions a program that’s controlled using a small keypad. The Centurion WS possesses three features that make it easy to maintain: a mistake monitoring and taste wood, on-board real-time movement images, and total on-board diagnostic checks. The Archon/OI Model 4552 does not possess these features.

An autosampler for purge and trap is an essential expense for separate analysts and labs that analyze shades and liquids using the GC/MC process. Although many laboratories utilize the Archon/OI Design 4552, it generally does not provide the same analytic superiority, physical robustness, production, simplicity, and simple preservation since the Centurion WS. For large labs and independent experts whose funding depends upon research cost and quality, the Centurion WS the best autosampler for purge and trap.

An autosampler automates the liquid testing method by operating on a designed time schedule, or with regards to situations that are interpreted by sensors. In either case, autosamplers increase the efficiency of fuel chromatography (GC) testing – an activity in which inlets were after filled by hand. Nowadays, scientists can choose between a few makes and types of autosamplers, of which the Cobra L/S water sampler is one of the best. Presenting an easy, lightweight style and easy functioning procedures, this autosampler presents these advantages, and others:

The equipment’s all-electric style enables labs to cut back operating costs by removing the need to obtain a company fuel for the portable phase. For big labs and services that have multiple labs, this may produce important savings. Some autosamplers have a restricted range of treatment and needle load charges, but the Cobra autosampler has a selection that accommodates that most challenging process requirements. Regardless of the GC testing method you apply, this autosampler may match its injection / syringe fill needs.

Preferably, an autosampler should use off-the-shelf syringes and maybe not private ones. In addition to charging more than off-the-shelf syringes, amazing syringes are hard to supply on a crisis basis. In medical devices, an RS-232 connection – rather than the common serial coach – is the most well-liked method for outputting information to computers, wherever it may be analyzed and archived.
