The IGL laboratory takes part in testing split samples or initializing them. The analysis of split samples can be defined as the analysis of a sample by a primary method (method used by laboratory x) and a comparative method (a similar method used by a y-certified laboratory).
The analysis can be performed by:
- A sample is actually divided into two parts, one part being analyzed by the primary laboratory and the other part by another certified laboratory using a comparative method
- Or the sample is analyzed in the primary laboratory and then the same sample is sent to the other certified laboratory for analysis.
Split samples can be used to determine the following:
- the relative accuracy of a particular test method;
- the linearity of an instrument compared to a reference instrument; or
- As a substitute for proficiency tests
- To verify the accuracy of testing of non-regulated analysts for which the laboratory does not take part in round robin tests.
We are strongly interested in generating as high a quality as possible. For this purpose we use state-of-the-art equipment, such as:
- The latest analysis kits
- The most modern methods in chromatography, e.g. mass spectrometry, gas chromatography, intracellular pH measurement and many more
- regular and intensified training of our employees at the highest level
- regular self-training and colloquia
- Attendance of congresses and international seminars
- Exchange of experience with other international scientists
- University connection
- Complete, automated documentation of all results from analyses, calibrators and standards
The IGL laboratory refers to the difference in results between two instruments analyzing the same samples. Differences are caused by different instrument technology and manufacture, the use of different methods to perform the analysis, or different reagents. We consider the analysis of split samples to be important because the bias between some instruments is large enough to affect the laboratory's evaluation. Ideally, comparison of results of an analyte between laboratories should be performed on identical instruments using the same procedure and reagents.
