Our Quality Control department

Our Quality Control (QC) department operates on a 24 hour basis. Each of our two sites has a QC laboratory equipped with the analytical equipment required to monitor and control the processes run on the plants on both of our sites. We have three QC Specialists, with over 60 years’ (combined) experience of working in a high throughput QC Lab. Each shift team has a dedicated QC technician to carry out all analyses during their period on duty.

A key role in compliance with our authorizations is that of the Environmental Chemist. He is responsible for monitoring new process introductions and routine production. This includes vent releases and effluent analysis.

Analysis of Raw Material, In-Process, Final Product and Environmental Samples is undertaken to the appropriate ISO 9001:2015 standards to meet our customers’ requirements.

The QC and R&D laboratories work together to develop and implement new analytical methods which may be required by customers.
