Autosamplers
- E-Nose analyzers can be coupled to autosamplers: storage (up to 96 vials), incubation, agitation, headspace collection and injection.
- E-Tongue system includes autosampler: storage (16 or 48 beakers), agitation, measurement
Advantages
- High throughput of analysis
- Automated operations
- Reproducible operating and analytical conditions
- Flexibility of devices and options.

In order to optimize headspace sampling or pre-concentrate volatile organic compounds, Alpha MOS proposes various sampling options prior to smell and VOC analysis:
- Solid Phase Micro Extraction (SPME) - Technical note (pdf)
- Solid Phase Dynamic Extraction (SPDE) - Technical note (pdf)
- In Tube Extraction (ITEX) - Brochure (pdf)
- Automated thermodesorption - Technical note (pdf)
- Headspace generation systems for large volume samples - Technical note (pdf)
- Petri-dish system with controlled temperature to directly measure the headspace above bacterial cultures (microbiology applications: monitoring of bacteria growth) -
Technical note (pdf)
- Measurement bell to assess the diffusion and longevity of a fragrance - href="../information/contact.html">Technical note (pdf)
- Flow cell for direct on-line analysis Technical note - Technical note (pdf)
Advantages
- Optimized sampling
- High sensitivity
- Increased selectivity
- Reproducible operating conditions.
Liquid & Solid Sampling Devices
Lab blender
|
Gravimetric dilutor
|
Two sampling accessories help optimize liquid and solid sample preparation prior to smell, VOC or taste analysis, especially for food & beverage applications:
- The gravimetric dilutor for automated weighing of the sample & diluent based on the desired dilution rate - Brochure (pdf)
- The lab blender for automated crushing and homogenization of samples, to transform solids into liquids and provide samples free of particles using filter bags - Brochure (pdf)
Advantages
- Insures that the analyzed portion of the sample is representative of the whole product
- Guarantees homogeneous & repeatable samples.
