THT and TBM in methane

This is a gas mixture containing tetrahydrothiophene (C4H8S) and butylmercaptan (C4H10S) in a range of concentrations, typically used to calibrate the instruments used in the odorization of natural gas.

This gas mixture is available in lightweight aluminum alloy cylinders in a range of capacities, from 5 liters to 50 liters.

The mixture is calibrated or produced in accordance with preparation and analysis procedures accredited by ACCREDIA and is therefore metrologically valid.
