Automated VOC Sample Prep System

The Atomx combines an Autosampler and Purge and Trap into a single instrument for the analysis of VOCs in soils and waters. This is the first of its kind and the only system that employs a unique methanol extraction automation feature for high level soils in accordance with USEPA Method 5035. Extractasol clean-up step (patent pending) in the Atomx reduces carryover or cross contamination normally associated with high-level water or soil analysis. Three independent injection systems for internal standards, surrogates, and matrix spikes provide the ability to select variable volumes without generating...

How It Works Atomx is a Purge and Trap (P&T) system, combining automation and concentration into one system for the analysis of solid and liquid samples. The system prepares P&T samples, including drinking water, wastewater, soils, and sludges. Atomx completely automates sample preparation and P&T steps including vial handling, sample volume measurement, standard injections, dilutions, rinsing, purging, desorption and baking. The Atomx single needle design transfers liquid sample aliquots from the vial to the sparger. Low-level solid samples are purged directly in the vial, transferring analytes...

80-Position Carousel Design for Optimal Throughput The carousel drive is an electronically controlled mechanism that positions sample vials for sampling. The carousel positions the sample vials by rotating the carousel and indexing. The carousel tray is removable from the drive assembly for easy vial loading. Mixer Assembly This assembly allows for a magnetic stir bar to be added to the sample vial of a solid sample. The Atomx has the ability to spin or agitate the vial when it is in the sampling station to mix the soil during the purge process, or to mix a soil for Methanol Extraction. Vial...

Sample Transfer Line A patented 3-stage sample needle is used to displace the sample from the vial, purge in the vial and complete Methanol extractions. Heated Sample Mount and Path The heated sample mount on the Atomx is programmable up to 100 oC and the sample path is programmable up to 250 oC. The entire gaseous sample pathway uses SilcoNert® 2000-coated surfaces and Inertium® tubing. Glassware 5 mL or 25 mL fritted, or fritless glassware available. Unit ships with 5 mL fritted glassware. Extractasol (patent pending)– Potential carryover can be reduced by as much as 50% with the dedicated...

VOC TekLink™ Fully Optimized User Interface VOC TekLink™ software allows the user to enter all analysis parameters and once activated, it will continuously monitor the system ensuring operating limits are not exceeded. VOC TekLink™ software is capable of performing useful diagnostics such as leak and benchmark tests for instrument validation. All instrument parameters, method scheduling and editing can be programmed. VOC TekLink™ provides pre-developed methods, allowing startup with little or no modifications and also contains an optional 21 CFR Part 11 data audit trail package. The Status section...
