Biomass Monitoring Applications

  • Premium

    Measurement of methane, methanol and ethanol for the biomass monitoring for biofuels.

    The Series 8900 provides direct measurement of methane, methanol, and ethanol for the biofuel industry. The Series 8900 GC employs a flame ionization detector (FID). The methane, methanol, and ethanol in the gas sample are physically separated using proprietary GC columns. A dual-column configuration with timed backflush to vent is used to strip off moisture and heavier gases. At sample injection, a fixed volume of sample is carried through the pre-cut column. The backflush is timed so that primarily the MME and other similar compounds continue on to the analytical column. Contaminants are then backflushed to vent. Methane, methanol, and ethanol are separated from potentially interfering components on the analytical column and elute to the detector for analysis.

    Oxygen monitoring from aerobic and anaerobic for biomass activity tests

    Pulse-Flow respirometers can be used to assess biomass activity for aerobic and anaerobic reactions. In aerobic tests, cultures are combined with nutrients, trace minerals, and an organic substrate – such as acetic acid or ethanol. The maximum oxygen uptake rate reflects the amount of active biomass in the test culture.

  • Microbial testing for personal care products sector

    The Problem: Microorganisms. personalcareMicrobiological contamination is a threat to product quality and process integrity in the personal care products and life sciences manufacturing industries – the purity of raw materials including water is essential to ensure manufacturing compliance. Microorganisms may be introduced at several stages of the process; subsequently, manufacturers must put in place stringent Quality Assurance / Quality Control (QA/QC) programs to manage microbiological contamination.
