Additional information

This test is ISO/IEC 17025 accredited through A2LA, Certificate # 2769.01.

Moisture is determined by measuring weight loss resulting from heating the sample in an oven under controlled conditions. Percent weight loss is reported for moisture. Percent weight remaining is reported for solids.

These methods are applicable to nearly all foods and food-related products. They are not applicable to samples containing large amounts of substances (other than water) that may volatilize when heated or subjected to vacuum. They are not appropriate for pure shortenings, oils, or high-fat samples. See Moisture (Karl Fischer) Titration Test for these samples.

Some samples (e.g. fruit slurries, fruit roll-ups) may be mixed with dried, ground filter paper and dried on a steam bath prior to insertion in the oven. This helps moisture escape through sugar or protein skin. In all cases, the sample matrix determines the conditions of the analysis (oven type, temperature, treatments, etc.).

Common Moisture Test Testing Questions

While our sales and customer service team are happy to answer general testing questions, consultations typically start at a rate of $250 per 30 minutes regarding the interpretation of reported test results or questions about our test methods. We cannot consult on regulations, tolerance limits, or claims.

We make every effort to keep our methods and detection limits up to date according to the latest standards and qualifications. If you have any questions regarding the limit of detection/quantification or method references, please contact our Customer Service team at 1-800-245-5615.

Our standard turnaround time is 10 business days for most assays. There are some assays that require a longer turnaround time. We also offer a RUSH service that is half the time of the standard turnaround time of the assay at double the cost of the assay. A few assays that we provide cannot be rushed due to the nature of the test. Please check the specific assay you are interested in regarding the ability to RUSH the turnaround time.
