Does Your Contract Testing Lab Pass the Test?
There are many contract testing labs in the market competing for your business. They may offer the particular test that you require, but how can you be confident that the data you pay for is accurate, precise, and conforms to the current best practices? It is up to you to put your contract lab to the test.
Here are some key questions you should ask:
Q. Does your lab offer full method and data disclosure for the
analysis of your sample?
ChromaDex™ offers an Analytical Test Report (ATR) which details the full
sample preparation procedure, analytical testing method, data, and results. HPLC and GC ATRs include the chromatograms while HP-TLC ATRs include the plate images. Alternately, the basic Analysis Results Sheet (ARS) is also available for routine testing. Complete documentation of the test method used is a crucial part of Q. Does your testing lab have the appropriate testing equipment?
ChromaDex™ is equipped with HPLC, GC, MS, UV, IR, NMR, and HP-TLC
testing capabilities. The equipment is maintained and calibrated regularly to ensure the accuracy of your data. Certain assays require specific equipment for data confirmation.

ChromaDex reference standards are characterized by a series of analytical
techniques that determine chromatographic purity, water and residual solvent content, along with MS and NMR confirmation. These analysis provide the minimal data needed to determine accurate reference standard purity. Reagent Grade chemicals are not reference standards and are not suitable for quantitative analysis. ChromaDex is the leading provider of reference standards in the industry and we use only characterized reference standards in our analysis.
Q. Does your testing lab use Laboratory Control Standards?
ChromaDex™ tests a Laboratory Control Standard along side samples being
analyzed to ensure method stability and reproducibility. By consistently testing this Control Sample along with the Reference Standard and customer sample, we are assured that the test is working properly and the results are accurate.
