Product Analysis and Laboratory Services

A-Gas laboratories have been constructed and equipped in line with the strict guidelines of AHRI 700 testing requirements. Our expert team provides analysis and related services through our state-of-the-art, on-site laboratories to ensure the quality of all products.

We’d love to tell you more. Contact Us.

Refrigerant Analysis

Our analysis services are ideal for use on systems that have operational problems or as part of a planned preventative maintenance program. Our services enable end users to test the working fluids of a running system and establish whether the fluids are contaminated. Our refrigerant analysis kit includes a sample cylinder, complete with full instructions and a submission form. The analysis test results will indicate identity and purity, along with problems with oil residue, moisture, acidity, and composition against the NIST libraries. Further testing for non-condensables and R40 (Methyl Chloride) can be carried out upon request prior to a sample being returned for testing. 

Product Identification Services

Utilising chromatographic separation and mass spectral identification, our testing and analytical services are offered on unknown inert gases, flammable gases and toxic gasses to help users identify what the product is.

State-of-the-Art Laboratories

Halon Analysis

Our laboratory services include the analysis of Halon 1301 and 1211 in accordance with ASTM D5632-08 Type I / II and ASTM D7673-10 Type I / II respectively. Our analysis verifies whether Halon 1301 and 1211 meet the required specification level for use as a firefighting medium. The parameters tested are purity, water content and acidity, along with a qualitative test for non-volatile residue and suspended matter. Our testing services extend to include non-condensable gases in Type II Halons.

Oil Analysis

Oil analysis can provide early warning of potential problems by identifying concentrations of metals and other contaminants in the oil. This can avoid unscheduled downtime and prevent damage to equipment. Our oil analysis kit contains a small bottle to take the oil sample and an instruction form which both need to be returned to A-Gas for analysis to be completed on your behalf.

Carbon Dioxide Analysis (CO2/R744)

CO2 Analysis

Refrigeration systems that contain Carbon Dioxide (CO2/R744) require strict controls on moisture, oil and other contaminants. Our CO2 analysis service enables end users to identify the purity and moisture levels of the product in the system. Our analysis cylinders have been designed specifically for liquid CO2 samples to be charged into the cylinder and our laboratory facilities have been set up to handle the analysis based on the specifications set by the industry standard. The correct sampling techniques and appropriate cylinders are essential for obtaining a meaningful analytical result (a standard refrigerant analysis cylinder is not suitable for this use).

Glycol Analysis

Glycol Analysis

The analytical services available from A-Gas can determine the overall health of Secondary Heat Transfer Fluids and the systems in which they operate. Such tests include:

  • Fluid pH – The pH of the fluid gives a good indication of its overall health. A low pH (<7 ) is generally indicative of fluid degradation and can lead to system corrosion if left unchecked. A high pH (>9.5) increases the risk of corrosion of certain metals.
  • Refractive Index and Freeze Protection – An accurate determination of freeze point provides reliable information on the protection offered to a system.
  • Biological Fouling – An aqueous based HTF and the systems in which they operate can be susceptible to biological fouling. A biological growth test can be conducted to identify fouling early and also to ensure disinfection is carried out successfully.
  • Conductivity – The electrical conductivity of a HTF can be used to detect the onset of corrosion.
