Sherwood Flame Photometer 410
Flame Photometry is the technique of choice for the measurement of Sodium, Potassium and Calcium in all sample types in: Mineral Extraction, Oil Industry, Paper Industry, Pharmaceuticals, Soil Analysis, Utilities, Food & Beverage, Chemical Manufacture and Fertilisers.
The Model 410 Industrial Flame Photometer with digital output, for printer or PC connection, also has Sodium linearisation capability to allow higher concentrations of Sodium (<40 ppm) to be directly measured using a single point calibration. That facility can be switched on or off according to the operator's preference or protocol for Sodium determinations.
The Model 410 Industrial Flame Photometer has Sodium, Potassium and Calcium specific filters and NIST traceable 1000 ppm standard concentrates for each of those analytes (6 x 100 ml).

Technical Specifications:
  • 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: ( To be measured 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
  • Height: 51cm
  • Width: 34cm
  • Depth: 39cm
