Which solution is better for your business?
We are often asked to outline the advantages of using on-site test kits in place of shipping samples to laboratories for testing. When both processes are compared, in theory the results are the same, i.e. a full report on the status of your fuel in relation to Microbiological Contamination. In practice there are huge differences in terms of time and expense:
On-site FUELSTAT® testing kits
FUELSTAT® Plus is offered in two different variants for Diesel and Jet Fuel. All equipment required to conduct the test is contained in each kit, including full instructions. A free FUELSTAT® Result app is available for all users that can be instantly downloaded onto any smartphone and contains step-by-step video instructions that can be followed to ensure correct use of the test kit, every time. The app also includes a digital reader that will scan the completed test and will give an immediate result of the test, together with a test report that can be printed and emailed anywhere in the world.
- Ultra simple test that requires 4 drops of sample
- 15-30 minutes from sample to result and report!
- Carried out on site, so complying with ASTM D6469 – testing for contamination within 24 hours
- Avoids time delays and expense associated with sample transportation to laboratory
Off-site Laboratory testing
Many companies have been using either independent or self-owned laboratories around the globe to conduct their fuel testing. A variety of techniques are used, the end result is a test report delivered stating the levels of Microbiological Contamination in the fuel sample received. Whilst standard terms of service may be agreed, the time taken to receive a report on which to act is governed by the shipping time, goods received protocols and current test backlog at the lab. Most companies will quote a 4-7 day lead time for results, but the reality may be much longer.
The main concerns voiced by many operators are that both biological and nonbiological deterioration processes continue in a sample during the period between collection and analysis. Put simply, is the contamination in the sample that is being tested at the lab the same is that in the fuel storage tank?….
To address these concerns ASTM have provided their document ASTM D6469 – Standard Guide for Microbial Contamination in Fuels and Fuel Systems.
BEST PRACTICE – Section 8.3: “Ideally, all testing should be accomplished at the sampling site, within a few minutes after a sample is drawn”
- FUELSTAT® tests comply with ASTM D6469 Section 8.3
REALITY FOR MOST OPERATORS – Section 8.5: “Rarely possible, good practices for preserving and preparing samples for analysis should be followed”
So what are the good practices?
- “Samples for Microbiological testing should be kept on ice for transport to the laboratory.”
- “Tests should be performed within 4 hours and no later than 24 hours after sampling.”
- “Samples stored at higher temperatures, or for longer times, can show the presence of microbiological contamination that does not represent actual fuel system conditions.”
