QA System

1 2

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

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
