George E. Booth Co., Inc. offers BWB Technologies flame photometry. In principle, a flame photometer is a controlled flame test with the intensity of the flame colour quantified by photoelectric circuitry. The sample is introduced to the flame at a constant rate. Filters select which colours the photometer detects and exclude the influence of other ions. By employing modern technology the customer can measure 5 elements (Na, K, Li, Ca and Ba) very simply but with extremely accurate results.
