Spectrometer operating costs
The spectrometer operating costs mainly comprise:
Electricity: about 40w on standby
about 700w during sparking
Ar: 5L/min during analysis
The operating costs for spectrometer with SDAR ARE basically determined by Ar consumption, and Ar consumption is determined by the number of samples. For a foundry with 100 samples in 8 h over 2 shifts without weekend work on the one hand, and a test room with 20 samples in 8 h over 1 shift without weekend work the operating costs are calculated as under:
a) Foundry
For 100 samples plus recalibration and control samples, the spectrometer will spark for min in 8 h.
Analytical flow 5h*200L/h=1000L
If the Ar is supplied from individual bottles, the cost are 250 DM /week or 1000DM/month or 12000DM/year.
For electricity, electrodes, recalibration and control samples the costs are ≤10% of the above.
b) Test room
For 20 samples plus recalibration and control samples the spectrometer will spark for 60min in 8 h.
Analytical flow: 1h*200L/h=200L
Approximately equivalent to 400L in 8 h or 2000L 1/5 days or 40 DM/week or 160 DM/month or 2000 DM/year.
