Automated SIFT-MS

   Automated SIFT-MS is the result of the collaboration between GERSTEL and Syft Technologies to provide automated platforms for SIFT-MS solutions in routine and R&D laboratories.

Autosampler integration is the simplest and most cost-effective way to fully realize the high sample throughput potential offered by SIFT-MS based on rapid, direct gas analysis. In addition, an autosampler improves repeatability and reproducibility compared to manual operation while reducing the risk of operator error.

SIFT-MS is a direct mass spectrometry technique that doesn’t require chromatographic separation and the associated extended analysis time waiting for individual compounds to elute from the GC column. Autosampler requirements also differ from those of standard GC or GC/MS techniques for which rapid injection techniques are needed: SIFT-MS requires steady sample injection for the duration of the analysis, because injection and analysis are performed simultaneously.

The GERSTEL Multipurpose Sampler (MPS) has proven to be the best-suited standard autosampler for SIFT-MS. Through joint development projects, the MPS and MAESTRO software have been optimized for SIFT-MS analysis providing an integrated system with access to a wide range of sample introduction technologies and applications for routine-, contract- and R&D laboratories.

Syft Technologies Voice200 series SIFT-MS instrument: Platform capable of high-throughput gas and headspace analysis for VOCs and inorganic gases. Multiple inlet options are available, including solutions integrated with GERSTEL sampling technologies for rapid automated analysis.

 

GERSTEL MPS robotic Autosampler: Multi-purpose sampler available with wide range of accessories to meet a wide range of automated analysis needs, including sampling from Headspace vials, sample (tedlar) bags, whole air canisters and sorbent tubes for thermal desorption.

Available sampling techniques:

Headspace sampling from headspace vials up to 100 mL volume

Automated SIFT-MS provides unparalleled throughput for headspace analysis

Multiple Headspace Extraction (MHE)

MHE is a method that enables the calculation of the total amount of a given compound from a limited number of consecutive headspace analysis steps. Using SIFT-MS combined with the GERSTEL MPS, a 6.5-fold increase in throughput is achieved compared to GC/MS.

Tedlar® Bag Sampling

Gas sampling bags provide convenient and cost-effective sampling of VOCs and toxic industrial chemicals (TICs) in ambient air. Due to short residence times in the bag contents have to be analyzed quickly. Automated SIFT-MS provides quick analysis turn-over and high throughput.

Thermal Desorption

TD-SIFT-MS combines the selectivity, high sensitivity and real-time capabilities of SIFT-MS with the flexibility, inertness and efficiency of GERSTEL’s Thermal Desorption Technology.
