Premcem Gums is renowned and trusted for its high-quality products. Everyone right from Management to Production & QC personnel are committed to consistently deliver high-quality products that meet or exceed customer specifications.
Most of our products have raw materials which are natural in origin and which are processed in ambient conditions. In order to achieve consistent quality round the year, we have instituted a simple, rigorous and effective QC system which basically consists of testing at 3 stages as given below.
Although we have standardized processing parameters for hydration, grinding time, drying, etc. for different grades, it is the “in-process” testing which is effectively used to tweak processing parameters and to minimize the influence of i) slightly differing quality of natural raw materials and ii) ambient processing conditions which change round the year.
Our QC labs, at both Ahmedabad and Gandhidham, are operational 24 hours a day, and thereby ensuring not only raw material and finished-goods testing, but also continuous in-process testing.
Microbiology laboratory
Our Microbiology Lab
Pouring standard media into test tubes
Pouring sample onto petri dish for incubation
Unlike many other Guar Gum producers who get their Guar Gum samples tested for microbiological parameters at external labs, we have an in-house, operational microbiology lab to test for the following:
- Standard Plate Count
- Yeast
- Moulds
- E. Coli
- Coliform
- Salmonella
QA / QC personnel
The Head of our QA function is an Engineer and a BVQI certified Internal Auditor for ISO 9001:2008.
Our chemists are well qualified, with an average tenure of 11 years at our labs.
Lab processes and controls
- Testing equipment is calibrated once a year externally
- Viscometers are internally checked every morning against standard viscosity fluids supplied by Fann and Brookfield
- We routinely participate in ring tests with customer laboratories
- Post-shipment samples are retained for 2 years from date of production
