Automated VOC Sample Prep System - Model: Atomx XYZ
The Atomx XYZ Automated Purge and Trap VOC sample preparation system is designed for versatility and function. As the only combined automation/concentrator platform on the market today, it is also the only system capable of automated methanol extractions for high-level soils in accordance with USEPA Method 5035. Reaching beyond previous benchmarks, the system includes improved moisture control, a precision-machined valve manifold, reduced overall system footprint, increased 84 VOA vial capacity and rapid trap cooling. These refinements result in less water transferred to the GC, simplified plumbing, more bench space and increased throughput.
  1. Features
  2. Specification

The Atomx XYZ is the second generation combined soil/water autosampler and purge and trap concentrator system in the Tekmar VOC product family. It is the only instrument of its kind to employ a unique automated methanol extraction feature for high level soils in accordance with USEPA Method 5035. Methanol rinsing, dilutions capability and three standard addition vessels all come standard on the Atomx XYZ. While priced competitively, the system offers unique features that cannot be found on any other sample prep system on the market today.​

*Applications and Industries 

VOC sampling and analysis are used in a wide range of applications in the following industries: 

Environmental

Food and Beverage 

Pharmaceutical 

Flavor, Fragrance, and Packaging 

Petrochemical.

*Methods 

USEPA 502.1, 502.2, 524.2, 524.3, 524.4, 503.1, 601, 602, 603, 624, 5030, 5035, 8010, 8015, 8020, 8021, 8030, 8240, 8260

ASTM and Standard Methods Massachusetts VPH and GRO Methods​.

*Syringe Drive

Accurately dispenses sample volumes from 0 to 25 mL in 0.1 mL increments. Precision is ensured by purging air bubbles from the syringe valve with an aliquot of sample.

*Sample Elevator

The sample elevator includes a vial heater and variable speed mixer for in-vial samples and soils. A vial stripper bar eliminates the possibility of vial/sample needle interference.

*XYZ Automation

The quick, whisper-quiet arm has undergone years of refinement and testing to eliminate the issues typically associated with older XYZ autosampler platforms.

*84-Position Sample Tray

The 84-position sample tray loads quickly and increases capacity over previous models. A chiller tray option is also available.

*Advanced Moisture Control System (MCS)

Designed to reduce water vapor transferred to the GC system by 50% over previous models. Efficient enough that dry purge time can be minimized and cycle time reduced.

*Simplified Trap Access

Ample analytical trap compartment with access door and easily reached trap connections make routine changes quick and easy.

*Improved Trap Cooling

Up to 22% faster than previous models due to a powerful fan and dedicated ducting that draws cool outside air, rather than heated air from within the instrument.

*Redesigned Valve Manifold

A precision-machined manifold reduces plumbing connections by 52% over previous designs and results in improved system reliability.

*Single Platform System

Combining the concentrator and soils/waters autosampler saves bench space and simplifies consumables, parts and service.

*Additional Features

Automated Methanol Extraction (ME)- Only system capable of sampling low and high-level soil samples (>200 ppb) and automating the methanol extraction process.

Mass Flow Controller (MFC) - The digital MFC (patented) provides independent programmable flow control and simplifiesmethod optimization for water and soil sample types.

Methanol Rinsing – A unique methanol rinse reduces potential carryover by as much as 50% by cleaning the needle, sample lines, and glassware.

Autodilution - Capable of sample volume dilution up to 100 times (based on 5 and 25 mL sample volumes). This feature also has the ability to extract 50 or 100 μL volumes for ME requirements.
