Reliable purification

Suspended particles and matrix material in a sample may significantly influence analysis results and system stability. Removal of particulate matter from a sample or extract prior to analysis is therefore critical for many GC/MS- and LC/MS analysis methods, particularly when large series of samples are analyzed automatically. Besides, filtration is an integral part of many manual sample preparation routines

Integrated into the procedure

The GERSTEL MultiPurpose Sampler (MPS) cleans up to 196 samples in a single automated sequence using a wide range of standard luer-lock syringe filters. Filtration is performed as an integral part of the automated sample preparation, for example combined with centrifugation, derivatization, addition of standards and introduction of the cleaned and prepared sample to the LC/MS- or GC/MS system.

100% software control

MAESTRO software operates all GERSTEL modules and system solutions in a simple, intuitive and efficient manner. Sample preparation and analysis are performed in parallel thanks to the MAESTRO PrepAhead function for best possible productivity and system utilization.

Filtration optin benefits:

  • Filtration is performed as part of the overall automated sample preparation process
  • Time saving through elimination of manual steps
  • Laboratory staff experiences an improved work environment
  • Rugged operation, reliable and reproducible results, identical treatment of all samples
  • High sample throughput and best possible utilization of the analysis system through PrepAhead productivity: Filtration is performed during the ongoing analysis of the preceding sample(s)
  • All common syringe filter (Luer lock) types can be used
  • Manual methods can be transferred directly and automated. Method parameters are easily modified
  • One or more 98-position trays for 4 mm syringe filters can be mounted onto the MPS, enabling high throughput operation overnight and during the weekend – even when analysis runs are short
  • The 12-position MPS Filtration Tray enables automated filtration using different size syringe filters for maximum flexibility since any suitable standard syringe filter type can be used(4, 17, 25 or 30mm)
  • Filtration can be performed using open or sealed vials as per the user requirements

Filtration and GC sample introduction:

  • Reliable results without risk of injection needle blockage
  • Longer life expectancy of inlet liner and GC column since particulate matter is not introduced into the analysis system
  • Cost savings through a reduction in maintenance work and improved system up-time

Filtration and LC sample introduction:

  • Reliable results through protection of the LC column
  • Cost savings due to longer column life expectancy, a reduction in maintenance work and improved system up-time
