 Standard Vessels

 Three 15mL standard vessels, UV-protected for added standard stability; Standard vessels  sealed under pressure for standard concentration  integrity.

 Liquid Samples

 Type of sample

 Includes  drinking water and wastewater; Liquid samples containing up to 15mm of sediment  when measured from the bottom of an upright  40mL vial.

 Sample Glassware

 The system is capable of operation with 5mL or 25mL frit or fritless U-shaped sparge vessels.  Ships standard with 5mL fritted glassware.

 Sample Dilutions

 Programmable automatic aqueous sample dilutions of 1:100, 1:50, 1:25, 1:10, 1:5, 1:2.

 Blanks

 Automatic blanks can be pulled from the blank water reservoir and spiked with standard  allowing all autosampler positions to be used for  samples.

 Cycle Time

 Total Purge & Trap cycle time of less than 20 minutes.

Low-Level Solid Samples

 Type of sample

 Includes all types of natural soils and sediments. Sampled: Direct purge in the vial per USEPA  5035 low-level soil methodology.

 Sample Needle

 A patented 3-stage needle allows for DI water and standards to be directly added to the vial  where the solid sample will subsequently be  purged.

 Vial Heater

 Variable heat control from 35°C to 100°C.

 Mixing

 The solid sample can be mixed via a stir bar using three variable speeds.

High-Level Solid Samples

 Type of sample

 Includes all types of soils and sediments. Sampled: Automated Methanol Extraction and  subsequent dilution per USEPA 5035 high-level soil  methodology.

 Extraction

 Methanol can added directly to the vial containing a solid sample where it is mixed and  allowed to settle. The methanolic extract is then pulled  from the vial and diluted for  automated Purge & Trap analysis on the system. If high-level solids were sampled in the field  with the extraction  solvent and standards added the sample can be mixed and allowed to  settle prior to the methanol being pulled and diluted. The extraction  method offered complies  with USEPA Method 5035 for high-level soil samples.

 Matrix Spike

 The system is configured to allow a standard 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 5mL sample  volumes.

System Control

 Instrument Control

 TekLink™ software in a Windows® XP or greater environment. Via RS-232 or USB converter  (optional).

 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 Identileak  System Check, which has built-in diagnostics that  once a leak has been identified, the system  will check 3 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.

 Email Alert

 The system can be configured to send an email to alert the user of schedule completion or  stoppage.

System Accessories

 Cryofocusing

 The system can be configured with an optional Cryofocusing Module and will allow for  reconcentration of the sample at the head of the column  to improve peak shape. The  Cryofocusing Module is capable of trap temperatures down to -190°C (based on 75 psig of  liquid nitrogen).

 Sparge Vessel  Heater

 The system can have an optional sparge vessel heater added that will allow liquid samples to  be heated during the purge mode to  temperatures between 35°C and 90°C.

 Vial Cooling

 Optional vial chilling allows for sample vials to be held at 4°C until they are sampled.

 Foam Eliminator

 The system can be equipped with an optical foam sensor that will sense any foaming during  purge. The sensor can be configured to add anti-  foam agent to the sample so that the  sample can be completed, if these attempts to control the foaming do not work the sample  will be a  aborted and drained to minimize the risk of physical damage to the system.
