Simple Quantitative Measurement of Nannochloropsis Micro Algae in Water Using Shimadzu UV Micro Algae Analysis System

In studying micro algae, measurement of the daily growth (concentration) is important. Currently, this measurement is conducted by the dry weight method, in which the sample is filtered using filter paper, and then dried prior to weighing. However, a simpler, faster method is being sought to replace this time-consuming dry weight method.
Here, we introduce Shimadzu's newly developed UV micro algae analysis system which permits simple measurement of the micro algae concentration using a spectrophotometer. Measurement of a single sample can be accomplished very quickly in about one minute using a disposable screw-cap vial (or disposable cell).
This Application News introduces an example of measurement of Nannochloropsis micro algae using the Shimadzu micro algae analysis system.
