Certified long-term-stable reference material for somatic cell account
Application Frozen or lyophilized long-term-stable standard for calibration/adjustment of cell account analysers
Matrix Cow milk
Parameter/Conzentration 100.000 – 1.000.000 somatic cell/mL
Reference value Please refer to our product- and price list
Advantages The somatic cells were analyzed in multiples in seven different ISO/IEC 17025 accredited laboratories using automated fluorescence optical counting and one ISO/IEC 17025 accredited laboratory using microscopic counting. The reference value is the arithmetic mean of all statistically checked measurement results. Accuracy of the reference value was ensured by comparison with the robust mean. In two fluorescence-optical devices used, six results where returned to the reference values of the Golden Standard ERM-BD001 of the European Commission.

Certified long-term reference material – Inhibitor
Application Verification of inhibitor test systems, comparisation in the evaluation of results in routine analysis
Matrix Cow raw milk, UHT-Milk
Parameter Positiv-Control of MRL-Niveau / Negativ-Control inhibitor free
Reference value Please refer to our product- and price list
Advantages The concentration in the positive control sample corresponds to the MRL-Niveau (maximum residue limit accourding (EU) No. 37/2010), which means that the standard can be used to assess routine results.
