Submission Procedures

These procedures are recommended for the purpose of completing your analyses as accurately, efficiently, and promptly as possible.

Information Sheet

Please fill out the appropriate submission form completely. Detailed information is particularly needed for the names of researcher and student (if applicable) and complete address (especially Department or location) and telephone number and E-Mail address. This prevents guesswork when reporting, billing, or if we have questions.

Study Name

The study name that you choose is critical. It enables us to track the study accurately and enables you to identify it when the results are reported. If there are to be regular, periodic, or subsequent studies on the same or related project, please discuss the study name with one of the full-time laboratory staff.

It is crucial to the integrity of your data that your studies are clearly identifiable from each other.

Sample ID

Please number your samples with a simple and sequential number scheme. If you have complex sample IDs, it may be safest to assign simple numbers to your samples for submission to the lab and keep a key for yourself to correlate with your longer sample IDs.

A written or printed sheet with sample IDs is always helpful to the lab, especially for larger studies. An alternative for longer sample IDs is to provide a spreadsheet file of your sample numbering system. This saves retyping (and possible errors) when reporting results and when labels must be prepared.

Sample Labeling

Label your samples clearly. If the IDs are handwritten, print clearly and remember that "permanent" marker can be scratched off plastic cups or bags fairly easily. Please make sure that there is sufficient information on each sample to distinguish it from other samples and to identify it according to your plan for the study.

The best is a printed label on each sample submitted with name, date, study, and sample ID information.

Amount of Sample

Please check if you have enough material for testing. Soil testing requires 100 to 200g before drying. Plant material analysis requires at least 50g of dry tissue or grain before grinding, and water analysis requires 50 to 100ml.

While these amounts depend upon the tests requested and the type of sample, please check with the laboratory staff before taking your samples. If you have only limited quantities of material, talk to someone in the lab before leaving the samples. When limited quantity is available, tests may need to be prioritized, since there may not be enough material to run all the tests requested.

Analysis Time

Turnaround time for completion of analyses varies depending upon sample type, sample preparation required, tests requested, and the lab workload. If you have a deadline or special requirements, please notify us when you submit the samples.

It may be necessary for the lab staff to estimate the completion time for the analysis of your samples.
