The instrument will now perform the laser frequency calibration routine. This will take a
few minutes. When the calibration has completed, the result is displayed. The
instrument in now laser frequency calibrated.
In the unlikely event that the laser frequency calibration routine should fail, please perform a
wavelength calibration and repeat the laser frequency calibration.
NOTE: If the calibration fails again, please contact your PerkinElmer Service Representative.
SOP-12: Intensity Calibration
The intensity calibration must be performed using the National Institute of Standards and
Technology (NIST) Standard Reference Material. NIST SRM 2241 is the relative intensity
correction standard for Raman spectroscopy when using 785 nm excitation.
NOTE: NIST calibration is temperature dependent. If you intend to perform quantitative
analyses, you should ensure that your instrument is NIST calibrated at the
temperature at which data is to be acquired. Otherwise, any data should be used for
qualitative analyses only.
The NIST intensity correction is valid in the recommended operating temperature
range 20
°
C – 25
°
C. If you move the instrument to an environment outside this
temperature range, that is 15
°
C – 20
°
C or 25
°
C – 30
°
C, we recommend that you
perform a NIST intensity correction at this new temperature.
Contact your PerkinElmer Raman Business Unit if you wish to set up a NIST intensity
correction for a different temperature range.
Intensity calibration should typically be performed on an annual basis – that is, during an
annual instrument service – but also whenever the instrument is moved, following a service
repair or when there has been significant temperature variation in the local environment.
NOTE: As intensity calibration is not required on a regular basis, NIST Standards are not
included in the basic RamanStation 400 package. Standard Reference Materials can
be purchased from PerkinElmer (L1321831). Your instrument will be intensity
calibrated prior to shipping or during installation.
NOTE: The intensity calibration should be performed for each sampling accessory. In the
case of the RamanMicro 300 Accessory, an intensity calibration is required for each
objective lens.
