QuenchGone21 Specialty (QG21S™)

  • QuenchGone21 Specialty Standard Test Kit (QG21S-50) provides materials to perform 50 analyses each of Total ATP (or tATP: living plus dead biomass) and Dissolved ATP (or dATP: dead biomass only). This provides the most accurate indication of living microorganisms only via Cellular ATP and allows computation of the Biomass Stress Index to assess microbial population health.
  • QuenchGone21 Specialty tATP Only Test Kit (QG21St-100) provides materials to perform only 100 analyses of tATP. Use this kit when no differentiation between living and dead microbes is required.
QuenchGone21 Specialty (QG21S) test kits provide a real-time and complete measurement of total microorganism concentration (and optionally, stress level) in raw materials, intermediates, and finished chemical products. Use this information to identify process contamination and/or spoiled product immediately enabling swift action to be taken to re-work or scrap contaminated product, ultimately leading to shorter production cycles and faster time-to-market!
FeaturesTechnical DataApplications
  • Measure only living biomass via Cellular ATP.
  • Measure biomass health via the Biomass Stress Index.
  • Results available in < 5 minutes.
  • Low Detection Limit is nominally 5 pg/mL, thereby providing ample detection range for any control program for chemical preservation situations.
  • All interferences such as viscosity, color, residual chemical, and other characteristics inherent to sample matrices are mitigated.
  • All materials are stable for two years at room temperature.*
