|
Cycle Time:
|
Total Purge & Trap cycle time of 18 minutes, or less depending on the method.
|
Low-Level Solid Samples
|
includes all types of natural soils and sediments. Sampled: Direct purge in the vial per USEPA 5035 low-level soil methodology
|
Sample Needle:
|
A 3-stage needle allows for water and standards to be directly added to the vial where the solid sample will be purged.
|
Vial Heater:
|
Variable heat control from ambient to 90 °C.
|
Mixing:
|
The solid sample can be mixed via a stir bar using three variable speeds.
|
High-Level Solid Samples
|
includes all types of soils and sediments. Sampled: Automated Methanol Extraction and subsequent dilution per USEPA 5035 high-level soil methodology
|
Extraction:
|
System is capable of fully automating the methanol extraction of high-concentration soil samples.
|
Matrix Spike:
|
The system is configured to allow a surrogate spike to be added directly to the solid sample when the methanol is added for the extraction.
|
Extraction Dilutions:
|
Programmable automatic dilutions of methanolic extract of 1:100 or 1:50 for 5 mL sample volumes
|
System Control
|
|
Instrument Control:
|
Atomx XYZ TekLink™ software in a Windows® 7 or greater environment. Via USB
|
Method Scheduling
|
All method types can be run from any position in the sample sequence. Up to three standards can be added to any user-specified position. Multiple runs can be made from the same vial (not recommended).
|
System History:
|
The system records a complete history of all sample, schedule and method information.
|
Service
|
|
Electronic Leak Check:
|
Ability to leak check the entire sample pathway of the system via the automated System Leak Check. Built-in diagnostics that, once a leak has been identified, the system will check independent sub-systems for leaks.
|
Benchmark Test:
|
The system has a mode that will allow for full electromechanical testing including; valving, heaters, vial handling systems, liquid delivery system, inputs and outputs.
|
Diagnostics:
|
The system offers independent control of all valves, vial handling mechanisms and syringe drive for troubleshooting.
