3  Sample Analysis Guidelines

 

 

 

  Take care not to spill samples into the sample chamber.  Wipe up any spills promptly.  

 

  The cuvette MUST BE DRY on the outside when taking readings.  Any moisture or 

condensation on the outside of the cuvette can affect the reading. 

 

  Fill the cuvette with at least 3.5 mL volume (~ 

3

/

4

 full).   

 

  Use the same cuvette for your samples, it is very important that you thoroughly rinse the 

cuvette between samples.  CyanoFluor is very sensitive, therefore cross contamination 
between subsequent samples will skew results.  Three rinses with the sample intended for 
measurement will help flush out any residual and decrease the chance for cross 
contamination.   

 

  Do not use a cuvette cap as it may cause the cuvette to not seat properly in the sample 

compartment. 
 

  When handling the cuvette, hold it near the top. 

  Any bubbles in the sample will affect the readings.  Take care not to introduce bubbles into 

samples.  Remove any bubbles by lightly tapping with your finger on the outside cuvette wall 
or cover the top of the cuvette and tilt the sample to help dissipate bubbles. 

 

  Wait at least 3 seconds between consecutive measurements to allow the optics to return to 

normal state.   
 

  All samples analyzed should be within the specified concentration range 0 

– 100 µg/L; 

Samples outside of that range should be diluted with artificial seawater or source water 
filtrate to reduce inner filter and quenching effects.
