Testing of biogas is an important step in both the planning of a conditioning system as well as ongoing maintenance. When your gas sample test results are available, our trained staff will interpret the results, compare them to past samples, and make recommendations to keep your system operating at its optimum.
Please contact us for pricing, lead times, and additional details on how to sample and ship biogas samples, firstname.lastname@example.org.
We offer the following testing options to meet all your system requirements:
Following EPA Method 3C or ASTM D1945/1946 Methane (CH4), Carbon Dioxide (CO2), Oxygen (O2), and Nitrogen (N2) are reported in terms of their concentrations in the sample. The BTU calculation follows ASTM D3588. The relative density calculation is based on the major components.
Compound Speciation – Siloxanes
Total volatile organic silicon (Siloxane) speciation in gas. Analysis is completed by GC-AED or GC-MS following EPA Method TO-15, including TMS, L2, D3, L3, D4, L4, D5, L5, and D6
Compound Speciation – Sulfur Components
Following EPA Method TO-15 or ASTM D6968, Sulfur component speciation by GC-AED or GC-MS.
VOCs Full Panel
Following US EPA TO14/15/17 GC-MS analysis with GC-FID or GC-AED quantification at 0.01 – 0.2 ppmv level. Target components include all TO-14, partial and common TO-15, and characteristic Biogas VOC component excluding most branched or cyclic hydrocarbon components.
Shipping Biogas Samples
Shipping of biogas samples is regulated by the DOT. The sampling and shipping materials supplied by Unison meet or exceed all of these regulations.
