Abstract The methods for potassium and calcium in tobacco, based on column elution with dilute HC1 followed by flame photometry of the extract, were studied collaboratively by 12 laboratories. Potassium results were sufficiently precise to recommend that the potassium procedure be adopted as an official, first action method. Results for calcium indicate that additional study is necessary. Atomic absorption spectrophotometry offers considerable promise in overcoming many of the hindrances experienced with flame photometry, particularly the calcium measurement.
