Multi-laser-power calibration for quantitative determination of N and P in fertilizers by Raman spectroscopy A new method called multi-laser-power calibration (MLPC) is described for quantitative analysis by Raman spectroscopy. MLPC is based on the premise that, under controlled operating conditions, the intensity of Raman spectroscopy signals for a given analyte is directly proportional to the laser applied power used to generate that signal.

Automated standard dilution analysis using a four-port switching valve for fast inductively coupled plasma optical emission spectrometry determinations A switching valve accessory currently available in newer models of inductively coupled plasma optical emission spectrometry (ICP-OES) instruments is used to fully automate the standard dilution analysis calibration method (SDA).
