Good Sampling Techniques

Sampling Practices & Techniques

Our analysis is based on the sample submitted, which must be representative of larger batches or lots. We homogenize multiphase samples prior to analysis unless otherwise instructed.  Solid samples are ground prior to analysis for heterogeneous purposes, unless otherwise instructed. We also consider the sample container and holding time.

Confidentiality

Strict confidentiality on all client work is inherent with our service as an independent laboratory. Confidentiality Agreements, which are part of standard business practice for many clients, will be signed upon request. Reports or copies of any laboratory document will only be sent to you, unless written authorization is provided.

Quantity of Sample

CAL

Detection limit is based on sample size used. Please submit the appropriate sample size for best results and contact us for appropriate sample sizes.

Three to ten grams of sample is normally required for the determination of each element present in amounts greater than two percent. For trace analyses (ppm), several grams are needed for each determination. If your sample is limited in quantity, please contact us in advance for more exact requirements based on your required detection limits. (Please note that most test methods used by our laboratory are destructive in nature.)

Sample Containers
