Operation Overview
8.2 General Operating Guidelines
There are several general rules and procedures that should be observed while operating
the device.
NMR Measurement
During an NMR measurement try to minimize interaction with the SamplePro hr-MAS
system, e.g. exchanging samples, as this may disturb the NMR measurement results.
The laboratory supervisor should define procedures regarding access to the unit and/or
the 5 Gauss area around the magnet.
Sample Mix-up
The laboratory supervisor should define through an SOP who should be allowed to load
or unload samples from rotor containers, and when. The operator should work carefully
and, optimally, use rotor ID barcode collars.
ID Barcode
When the rotor ID barcode is dirty it should be cleaned according to established instruc-
tion or the barcode may be incorrectly read.
Contamination of Samples
Reusing rotors may result in contamination of a new NMR sample from the old sub-
stance. Clean reusable rotors in accordance to established GLP and SOP standards.
