Recently Asked Questions

PerkinElmer/LAMBDA 650/750 - Fan noises
Recently, the fan on the Lambda 650 sounds louder than normal. The readings are all the same and there seems to be no performance impact. It just sounds obnoxious and worrying to the users. Has anyone ever come across this issue/how did you fix it? Someone in our lab suggested a bearing adjustment might be needed in the motor, but it would be nice to have some guidance before I open up the whole machine. Advise this member.

The Role Of Purified Water In Solid Phase Extraction

Solid Phase Extraction (SPE) has become established over the past forty years as a versatile and powerful tool for pre-concentration in trace analyses of complex matrices including urine, blood, water, beverages, soil, and animal tissue. Recent developments1 and the inclusion of SPE in the EU programme for water analyses2 confirm the on-going role of SPE and I am taking the occasion to review the requirement for purified water in current SPE techniques.
