Frequently Asked Questions

How do I submit samples?

CSL has provided a Sample Submittal Form, which includes all of the information that we need to process your samples. This form can be filled out online and emailed to us or you can print out the form and mail it in with your samples. New clients must also fill out a New Client Information Form prior to submission.

How much sample do you need?

For solid and liquid samples (non environmental), we prefer 10 g (mL). This allows us enough sample to perform all of the necessary quality control. If you have a water sample, we require 250 mL in order comply with DEP requirements. We can work with less volume in some cases.

What are your detection levels?

Detection levels vary from element to element and also depend on the sample matrix. Please call us to discuss your detection requirements and sample type.

How long will it take to get my results?

Our standard turnaround time is five business days. Analyses can be expedited to provide three or one day turnaround. Please check with us on the availability and pricing for rush analysis prior to submitting samples.

What is PQL?

PQL stands for practical quantitation level, which is the detection level we use in reporting results.

What happens if I need to add an analysis to a sample I have already submitted?

If you have not yet received results, please call and we can add the additional test and update your sample submittal form. If it is a sample for which you already have the results, we can check as to whether we still have the sample and whether we have enough volume to run the analysis. New paperwork and sample may be required. All samples are retained for a minimum period of two weeks after testing has been completed.

What are the terms of payment?

Typically, invoices are sent out 2-3 times per month. Terms of payment are net 30 days. We accept payments by check, Visa, Mastercard, and Discover. New clients may be required to pay prior to analysis of samples.
