Sample Submission

You have samples you would like analyzed?

In order to submit samples for analysis it is best that our technicians understand the sample being submitted, as well as the results you expect to attain.

To assist us, please include the following in your submission:

Sample Requirements:

Mercury Analysis in Water

Samples should be collected according to EPA 1669.

If filtration is done in the field (prior to submission)


If filtration is not required

*NOTE:  If you are sampling the same site for MeHg and THg you don't necessarily have to send two bottles. As long as they have been preserved with HCl and NOT BrCl. 

Mercury Analysis in Sediments

Preference to at least 1.0 g of freeze-dried sample. Alternatively, approximately 5.0 g of wet sample is sufficient. Samples should be stored in small sealed Ziploc bags or equivalent. Samples should be frozen (if wet) and shipped in ice packed coolers.

Mercury Analysis in Fresh Tissue

Homogenized or representative sample of desired portion (e.g. liver, muscle tissue, fat, etc). At least 1.0 g of freeze-dried material or approximately 5 g of wet weight material. Samples should be stored in sealed Ziploc bags or equivalent. Samples should be frozen (if wet) and shipped in ice packed coolers.
