Determination of trace manganese and Ni in neem oil by ETA-AAS with emulsion sample introduction

An emulsion‐based method was developed as an alternative for the introduction of oil‐based samples into a graphite furnace to produce a more rapid, precise, and accurate method of analysis. The combination of emulsion sampling and electrothermal atomization for atomic absorption spectroscopy was dev...
