Volatile Fatty Acid (VFA) Profiling Service

Accelerated Research: Trust Our Detailed VFA Analysis

VFA is produced during the degradation of organic matter in anaerobic environments and is an important parameter for assessing Anaerobic Digestion. Analysis of volatile fatty acids is an invaluable tool for understanding microbial activity and optimizing anaerobic digestion parameters. Creative Biolabs provides a quality VFA analysis service with efficient analytical tools. We are happy to work with you to help you with your anaerobic digestion research.

VFA analysis process

VFAs are intermediate products of anaerobic digestion, such as acetic acid, isobutyric acid, butyric acid, etc. Our VFA analysis process is as follows:

Sample pre-treatment: This step involves extraction, purification, concentration of analytes, etc.
VFA detection: We have a wide range of advanced techniques to analyze, identify, and quantify VFA in various types of samples including Biomass.
- Ion chromatography (IC): This method involves simple pre-treatment, does not require separation through high temperatures, and gives accurate and reliable results.
- Gas chromatography (GC): GC is used to monitor changes in the concentration of VFAs in anaerobic digestion. VFAs are thermally stable and volatile compounds that are easily separated by GC and measured.
Data analysis: We calculate and analyze in detail the concentrations of VFAs.

Detection indicators

Our VFA analysis includes testing for the following seven substances.

Lactic acid
Acetic acid
Propionic acid
Butyric acid
lsobutyric acid
Valeric acid
lsovaleric acid

Published data

VFAs are intermediate in the methane formation pathway in anaerobic digestion. They can be used as green chemicals and raw materials for production. In this study, anaerobic digestion of cattle manure and food waste was evaluated. The changes in various VFAs were also detected by GC. By comparison, the researchers found that both wastes could be anaerobically digested to produce green chemicals and that the yield of VFAs was dependent on inoculum properties and substrate. This study provides a model for detecting and analyzing VFAs.

FAQs

Q1: What are the applications of VFA analysis?

A1: VFA analysis has a variety of applications and provides valuable insights for anaerobic digestion process optimization and feedstock suitability assessment.

Process monitoring: VFA analysis is used to monitor the anaerobic digestion process, and assess the efficiency of the process.
Process optimization: VFA analysis provides valuable information for understanding microbial activity and optimizing anaerobic digestion process parameters.
Substrate selection: VFA analysis helps to evaluate the suitability of different substrates for anaerobic digestion.
Digestate quality: VFA analysis provides information on the availability of digestate produced during anaerobic digestion.

Q2: What are the disadvantages of VFA accumulation during anaerobic digestion?

A2: Accumulation of VFAs is one of the parameters that should be considered during anaerobic digestion. Studies show that the accumulation of VFAs can lead to a decrease in pH, which inhibits methanogenic bacteria and leads to anaerobic digester failure, reduced methane production, etc.
