Quality Control & Chemical Laboratory

Quality Control Department and Chemical Laboratory

Laboratory quality control, analytical testing and systematic monitoring of product characteristics throughout production

Quality at every stage

Incoming control, production monitoring, testing, documentation and confirmation of batch stability

Laboratory capabilities

The in-house laboratory of Novoselivskyi GZK JSC controls the quality of raw materials and finished products throughout production. Testing uses modern analytical equipment and standardized methods to ensure stable characteristics for every batch

Controlled parameters

The laboratory controls key physicochemical and particle-size characteristics

  • iron oxide (Fe₂O₃) content
  • silicon dioxide (SiO₂) content
  • aluminium oxide (Al₂O₃) content
  • moisture
  • quartz sand particle-size distribution
  • silica flour particle-size distribution
  • loss on ignition
  • heavy fraction content for beneficiated quartz sands

Measuring instruments and equipment

Modern measuring instruments and laboratory equipment are used for testing

X-ray fluorescence analysis

  • Oxford Lab-X 3000
  • Hitachi High Lab-X 5000

Used to determine chemical composition and control major oxides

Particle-size control

  • laboratory sieves
  • sieve shakers
  • laboratory scales

Controls particle distribution according to the requirements of each product grade

Moisture control and sample preparation

Moisture control

  • moisture analyzer MA 210/C

Sample preparation

  • RETSCH vibratory mill
  • SNOL laboratory electric furnaces
  • laboratory scales
  • auxiliary laboratory equipment

Each customer receives

  • control of batch-to-batch stability
  • confirmation of compliance with technical specifications
  • quality passport (certificate) for each shipment
  • technical support in selecting the optimal grade

Systematic control throughout production

The laboratory verifies compliance with specifications during incoming control, production, storage and shipment.

Sample registration

A controlled system records samples received for analysis and their origin.

Measurement records

Laboratory measurement results are documented and traceable.

Quality passport

A quality passport can be issued to the customer on request.

Consistency monitoring

Continuous monitoring supports repeatable product performance from batch to batch.
