Operation Overview
8.2 General Operating Guidelines
There are several general rules and procedures that should be observed while operating
the SampleXpress.
NMR Measurement
Do not operate the unit, e.g. exchange sample cassettes, during an NMR measurement
as this may disturb the NMR system. The laboratory supervisor should define proce-
dures regarding access to the unit and/or the 5 Gauss area around the magnet.
Sample Mix-up
Sample mix-up from improperly read sample labels or position markings may result
when adequate lighting is not provided. Use the operator access position for monitored
sample loading/unloading, or place the cassette on a desk before loading/unloading
samples.
The laboratory supervisor should define who should be allowed to load or unload sam-
ples from cassettes, and when. The operator should work carefully and, optimally, use
tube ID barcode collars.
ID Barcode
When the sample ID barcode is dirty it should be cleaned according to established
instruction or the sample ID barcode may be incorrectly read.
Temperature Changes
When the ambient temperature changes significantly (for example, after moving the
SampleXpress from the stock room before mounting), wait at least 1 hour until the
device has achieved room temperature before turning on the device.
Contamination of Samples
Reusing NMR glass tubes may result in contamination of a new NMR sample from the
old substance.
