TriPlus RSH SMART Autosampler Sampling Techniques Overview

Topic

The TriPlus RSH SMART autosampler provides automated sample preparation and introduction for GC and GC-MS analysis.

The training covers three primary sampling technique groups:

• Static Headspace (SHS)

• Solid Phase Microextraction (SPME), including SPME Arrow

• In-Tube Extraction (ITEX)

The liquid sampling tool is not covered because the source training describes the liquid sampling concept as straightforward.

Environment

• Thermo Scientific TriPlus RSH SMART autosampler

• GC or GC-MS analysis

• Sampling tools discussed in the training:

  • Static Headspace

  • SPME

  • SPME Arrow

  • ITEX

Steps/Procedure

1. Select the sampling technique appropriate for the analytical application.

2. Use Static Headspace when volatile compounds need to be partitioned from a gaseous, liquid, or solid sample matrix into the headspace.

3. Use SPME when analytes need to be extracted onto a coated fiber before thermal desorption into the GC.

4. Use SPME Arrow when the application benefits from the larger sorption volume and surface area of the Arrow fiber design.

5. Use ITEX when volatile compounds need to be trapped and concentrated using a sorbent-containing micro-trap.

6. Configure the selected sampling technique within the applicable instrument method.

Additional Information

The training identifies the following benefits of the TriPlus RSH SMART autosampler:

• Rapid automation for GC and GC-MS sample analysis

• Robustness and reliability

• Flexibility through multiple sampling tools

• Reduced downtime

• Increased productivity and throughput
