The 7650 Canister Autosampler brings the automated analysis of MiniCans™, Bottle-Vacs™, and other large volume sampling canisters to a whole new level. Building upon the advantages of its predecessors, the 7650 is the first canister autosampler to facilitate the analysis of up to twenty, 1 to 1.4L canisters while maintaining samples in a completely closed and isolated state until required for analysis. This level of isolation greatly reduces the potential for carryover, making the 7650 an ideal choice for today’s soil gas laboratories. All samples, standards, and blanks, flow through the same direct flow path, eliminating any problematic background level variations – a well-known challenge with rotary valve based autosamplers.

The 7650 features a reliable and precise pneumatic z-axis control along with minimal transfer-line sample contact. The brief sample transfer process is immediately followed with an inlet-line nitrogen flush to further reduce any sample contamination risk. Since the Silonite® coated heated transfer line directly inserts into a MiniCan™ or Bottle-Vac™ canister via an ultra-compact MicroValve™ fitting, there is absolutely zero unswept dead-volume. When paired with a 7200 Preconcentrator, the 7650 becomes an ideal autosampler solution for today’s laboratories that must routinely analyze both high and low concentration samples.

The 7650 also includes an easily accessible, generous array of inlet expansion ports (in banks of 9), for the analysis of up to 18 additional canisters or Tedlar® bags. The 7650 has the ability to deliver sample canisters to an oven for heating up to 150 ̊C prior to analysis for the recovery of higher molecular weight compounds. A 7650 Loop option is also available for unsurpassed precision when analyzing PPM level samples.

Features

Analyze up to 20 MiniCans™ / Bottle-Vacs™
Holds 1 – 1.4L canisters in two, 10 position trays with intersample isolation far beyond that of rotary valve based autosamplers.

Toxic Organics Valvetm Compatibility
Now, add MiniCan™ autosampling for your canisters that use the popular TOV™ and Nupro® valves by simply attaching a MicroValve™ to the top of the sampler valve prior to analysis.

Silonite-D® Coated Inlet Lines
1/16″ heated Inlet line inserts directly into the canister MicroValve™ for a zero dead volume, secure sample connection. After minimal sample contact during transfer to the preconcentrator or GC/MS, the inlet line is immediately flushed with UHP helium or nitrogen – carryover is routinely less than 1 millionth the concentration of the previous sample!

Amazing Autosampling Capability
Analyze up to 18 additional 6L canisters or Tedlar® bags using expansion ports on the side of the 7650. Now, you can analyze any canister in your inventory using proven direct inlet reliability.
