Intertek has enhanced its sample cylinders services with the aim of providing further cost savings for clients. Sample cylinders are used by offshore chemists to transport live crude, gas and water samples from offshore to onshore laboratories for testing. Intertek has invested £180,000 in 200 high-pressure cylinders to meet an increased demand from clients for analysis services. Fifty cylinders will be specially coated to allow the safe and effective transportation of samples containing mercury and hydrogen sulphide. Both elements can adhere to the internal surfaces of standard stainless steel cylinders, rendering analysis unreliable.
