Dear Group members,

CASE: 1
sample processing should be done by single analyst or two or more can do the processing of the samples in a batch.
i mean to say if u consider a batch of 120 samples and the extraction procedure includes 8 steps. if first four steps are done by one analyst and remaining four steps by the other.

whether this type of processing is acceptable or not
if yes how?
if NO why?

CASE: 2
In a GLP lab is it necessary to use the instrument usage log books.
for example use of the refrigerator centrifuge and the SPE is it necessary to have a log book refering the usage of the instrument i.e start and end of the usage of the instrument.
yes or NO ?
with regards
Ramesh.V :-P

with regards,

Ramesh
