This document describes the use of the quartz fiber optic dip probe on the Cary 50/60 UV-Vis spectrophotometer to analyze the nitrate content in water.
Environmental laboratories use optical fibers to measure absorbance for analyzing ions like nitrates, phosphates, and fluorides. This document presents results obtained from measuring nitrate content in water using a quartz dip probe on the Cary 50 or Cary 60 UV-Vis spectrophotometer.
The standard solutions were prepared in a concentration range of 0 to 7 mg NO3-N/L.
Washing the probe with distilled water takes approximately 5 seconds.
The time taken to measure 24 solutions is approximately 5 minutes.
