Answer:It supplies potassium-specific spectral lines used in atomic absorption potassium measurements.
Answer:No. It is a single-element potassium source; combined Na/K lamps are separate products.
Answer:Compatible PerkinElmer PinAAcle and AAnalyst atomic absorption instruments use Lumina lamps.
The PerkinElmer Lumina™ potassium (K) hollow cathode lamp provides element-specific light for potassium determination by atomic absorption spectroscopy. This 2 in. (50 mm) single-element Lumina lamp is designed for compatible PerkinElmer AAnalyst™ and PinAAcle™ systems. In a potassium method, the lamp's characteristic emission lines pass through the atomized sample, where potassium absorption is measured against standards. The source can be used in validated elemental testing of prepared aqueous, agricultural or process samples. Potassium measurement can be sensitive to sample matrix and ionization conditions, so follow the selected AAS method for instrument settings and any required modifiers. Do not substitute the potassium single-element lamp for a combined potassium/sodium hollow cathode lamp without confirming the method and instrument requirements. The lamp is an optical measurement component, not a potassium chemical reagent.
