Support analytical competency and compliance with ISO 17025 recommended practice in IP 570/15.
Validation of apparatus performance is stated as a mandatory requirement at least every three months in IP 570/15. Participation in the Seta IP 570 Annual Proficiency Testing Scheme is the preferred means to achieve this requirement, enabling laboratories to evaluate their performance for testing H2S in the liquid phase using the Seta H2S Analyser.
Participants in the statistical quality assurance programme can continually monitor and compare their performance by analysing their data against similar laboratories in accordance with ISO/IEC 17025. This gives the ability to demonstrate compliance with laboratory accreditation requirements, identify any potential equipment or operational bias and provide added confidence to staff and customers. Ultimately helping to increase laboratory efficiency whilst reducing costs.

The H2S Verification Material is produced under our ISO 17034 UKAS accreditation. This aqueous solution contains a known concentration of liquid-phase hydrogen sulfide with a certified value. It is produced by accurately determining the mass of ingredients using a balance certified by an ISO 17025 accredited laboratory.
The H2S Verification Material is supplied in tamper-evident security packaging with full documentation, including a Safety Data Sheet (SDS). It has a three-month shelf life from the date of manufacture and is supplied complete with activator, two syringes, dispensing tube and silicone tubing.

The Temperature Verification Kit enables you to verify the operational oven temperature of the Micro Carbon Residue Tester (MCRT) (97400-3).
The kit consists of an oven lid which incorporates an iron constantan thermocouple, when placed on top of the MCRT oven the internal oven temperature can be seen during the test.
The temperature is displayed on a hand held portable digital thermometer which is supplied with a UKAS calibration certificate at the prescribed 500 °C test temperature.
