Sherwood Scientific Model 410 Flame Photometer
Flame Photometry is the technique of choice for the measurement of Sodium, Potassium and Calcium.
Ideal for use in the following applications:
- Mineral Extraction
- Oil Industry
- Paper Industry
- Soil Analysis
- Food & Beverage
- Chemical Manufacture
The Model 410 Industrial Flame Photometer comes with a digital output, for printer or PC connection. It also has Sodium linearisation capability to allow higher concentrations of Sodium (<40 ppm) to be directly measured using a single point calibration. The facility can be switched on or off according to the operator’s preference or protocol for Sodium determinations.

Sensitivity: To display minimum of 100 units, Na <0.5 ppm, K <0.5 ppm, Li 5 ppm, Ca 5 ppm, Ba 200 ppm
Specificity: For Na, K, Li interference is less than 0.5% of the concentration of Na, K, Li, Ca or Ba, equal to the concentration under analysis
Linearity: Better than 2% mid range with Na=3ppm, K=3ppm, or Li=5ppm
Drift: ( measure after 30 mins warm up): Zero Drift better than 2% per hour when calibrated with Na=10ppm
Reproducibility:< 1 % CV from the same Bulk sample for 20 determinations at Na and K=10ppm .
Limit of Detection: <20 ppb Na and K
Time to Stability: Aspirate for 20 secs.
Aspiration Rate: Variable 2-6 mls /min
