2. Click on Detector Calibration in the Spectrometer Control window.
The system automatically closes the shutter to measure signal bias and dark
current. The detector calibration routine may take up to twenty minutes.
Wavelength Calibration
The UV and VIS channel calibration gathers data for UV and VIS emission lines
to compensate for slight variations in optical alignment. At the end of the UV and
VIS wavelength calibration, the system determines the wavelength offset of an
emission line from the internal mercury lamp and records the slit position as a
reference point for future mercury realignments.
Since spectrometers are sensitive to thermal effects, it is important that the
Note
instrument be operated with the plasma on for at least one-half hour before
initiating wavelength calibration.
Wavelength calibration is performed in the following steps:
UV channel calibration
VIS channel calibration
Solutions you'll need for wavelength calibration include:
Wave Cal Solution (Part No. N0582152) available through PerkinElmer,
which contains 100 mg/L of P, K, S; and 20 mg/L of As, La, Li, Mn, Mo, Ni,
Sc, Na.
VIS Wavecal mix (Part No. N9302946) available through PerkinElmer, which
contains 1 mg/mL Ba, Ca; and 10 mg/L of La, Li, Mn, Na, Sr; and 50 mg/L of
K.
Rinse solution.
To initiate a wavelength calibration:
1. Make sure that the plasma is lit and has been on for at least 30 minutes.
2. In the Tools menu, click on Spectrometer Control.
The Spectrometer Control window appears.
