UV Micro Algae Analysis System

---

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). 

- Measurement of a single sample can be accomplished very quickly in about one minute using a disposable screw-cap vial (or disposable cell)
- The use of disposable screw-cap vials for these measurements eliminated the need for manual operations such as the washing of vials, which also eliminated any concerns regarding contamination and carry-over due to insufficient washing.

Concentration and Plot of reflectance at 910 nm


 

Using samples other than 70, 30 and 500 million cell/ml as standard samples, calibration curves of the single regression method (Primary calibration curve: Figure 3) and the multiple linear regression method were prepared, and the concentrations of samples of 70, 30 and 500 million cell/ml were quantitatively calculated. As shown in Table 1, the single regression method gives good predicted results, but multiple regression gives more accurate predicted results.

- The cell mass is large and the reflectance is high, a reflection method using a disposable sample bottle
- The cell mass is small and the reflectance is low,  a transmission method using a disposable cell.
