Quality Control

Siratech performs stable isotope ratio analysis to the highest standards possible. Quality control is maintained by constant attention to detail regarding the

    • proper handling, storage and preparation of samples,
    • by the proper maintenance and calibration of analytical instrumentation,
    • by the comparison and correction of analytical results through the use of internationally distributed reference materials and multiple laboratory standards and
    • by random and targeted replication of sample analyses.
All data are subjected to professional scrutiny for consistency in precision and accuracy. Customers are encouraged to submit internal standards or blind replicates for increased confidence in data. Analytical accuracy quoted is a combination of instrument as well as usual preparation effects of homogeneous samples. Apparent sample precision may be dependent on sample type, heterogeneity, size, and preparation requirements.
