Sample Submission Instructions


Analytical Request Form Download


Analytical Request Form 

Please complete an Analytical Request Form (ARF) as described below and submit it along with the samples. One ARF will suffice for several samples if the information requested and the test requirements are the same.

Typically, all testing requirements are known. However, if you are unsure of tests needed, contact our technical staff. In addition, there may be more than one method that can be utilized for the test requested – if specific methods are required, please specify on the Analytical Request Form.

If further instructions are required, please include this in the Notes & Comments section, or include an accompanying letter. 

Determine Sample Size

A reference table is available that lists some common tests, their methods, and the amount of sample required per analyte range. The amounts listed are only a guide and are generous in nature to allow for various methods and possible retesting. Keep in mind that for some sample types, we may not be able to remove the entire amount of a sample from its container. If your sample may be difficult to retrieve from its container, please send enough sample to allow for this process. 

If the sample is limited, please contact our technical staff for a calculation of a more precise amount. We will need to know the type of sample and the analyte range or required detection limit for each analyte.

Type of Service

Turnaround Time

 Check the desired turnaround time. Our standard service is approximately 10 business days. This service is subject to fluctuation as demand changes. 


Select the number of replicates that need to be performed for your sample.

Data Delivery 

If you would like to recieve certified copies of the raw data produced during testing, check this box. 

Special Handling

Check any special handling conditions that apply. “Dry before analysis” is non-quantitative. For a quantitative loss on drying determination, cite “Loss on Dyring” or “LOD” under the “Test Requested” section. 

Payment Information

Quote Number 

This is important to ensure the testing is completed as quoted.

Purchase Order Number 

If paying by purchase order, please list the number. 

Credit Card 

If you would like to pay your bill by credit card, we accept Visa, MasterCard, and American Express. Please do not include credit card information on the Analytical Request Form. When testing is complete, we will contact you to obtain credit card information and authorization to charge your card.

When using a credit card, a 4% surcharge will be added to the cost. 

Regulatory Information

  • Check the regulation that applies. Contact us if you are not sure.
  • We are a GLP/GMP compliant facility.
  • If your provided theory/range values are regulatory specifications subject to an Analytical Investigation in the event of an out of specification result, indicate this by checking “Yes” below the Testing Information table on the ARF.

Sample Information

  • For multiple samples, list your sample ID’s separately and the approximate amount being provided.
  • For sample composition, please describe the material in detail. Additional characteristics such as melting point (MP), boiling point (BP) or other known information can also be added to Notes & Comments.
  • Always provide a Safety Data Sheet (SDS) when available. We understand that many experimental materials may not have an SDS available; however, we do ask that you provide us with sufficient information so that we can handle your sample safely.
