Samples should be submitted with the appropriate documentation - MSDS sheets and method of payment information.

Please include as much information as possible on the sample - possible structures, expected results, solvent solubility.

NMR experiment requirements (if possible).

Send the PNA NMR Service Request Form with the samples.

Customers should indicate if the samples are to be returned after analysis or disposed by PNA (charges apply).

Liquid- and solid-state experiments:  provide up to 2g of sample. If sample quantity is limited please call with details.

¹³C Experiments require 500 milligrams for quantitative data to be obtained in a timely manner.

¹H Experiments require less sample and several mg is sufficient to obtain a spectrum within 1 hour of operation.

Sub-milligram quantity samples must be arranged beforehand as special NMR tubes and solvents/standards must be prepared.

Process NMR experiments : send 2 ounces of sample.
