For SigTests®: Sig Sulphide®

What is the test?

The test consists of a screw-capped, glass tube half filled with a selective microbiological culture gel that semi-quantitatively indicates the presence of sulphide generating bacteria by the rate and extent of the development of a black colour. The sample is added to the tube which is kept warm (incubated) for up to seven days; results are examined at regular intervals.

What is the test used for?

The Sig Sulphide test is used to detect the presence of microorganisms that can generate corrosive sulphide, e.g. Sulphide Generating Bacteria (SGB) including Sulphate Reducing Bacteria (SRB).

What can I test with the Sig Sulphide test kit?
  • Closed Water Heating and Cooling Systems
  • Bilge Water
  • Ballast Water
  • Fuel Tank Water Bottom
  • Metal Working Fluids
  • Process Waters, including coolants
  • Water associated with Lubricants
  • Environmental Waters
  • Soil, mud and drill core samples.
  • Metal surfaces which are prone to attack by SRB. A sterile swab can be used to swab surfaces or corrosion pits then thrust into a Sig Sulphide tube
What are the advantages?
  • Quick, easy and safe to use
  • Heavy infection is detected overnight. Much faster than the standard laboratory test method NACE TMO194-94
  • Simple to read results
  • Results are semi quantitative and give an indication of the severity of an infection
  • Many times cheaper than a laboratory test for sulphide generating organisms.
Who can use the test?

Full instructions are supplied and no special training is required to use the Sig Sulphide test.
