    Introduction 1.1 Description The Ballast-Check 2 is configured to provide users with a rapid estimation of algal abundance (Corrected Fluorescence or CFl) and photosynthetic efficiency (Activity) of algae in water. The CFl (see section 4.1) value represents varying algal abundances used for determining gross exceedance of algae in ballast water samples around the set threshold level.

    FAIL will display 2.4 Filtering Samples The Ballast-Check 2 comes with 3 types of filters that are used to analyze a sample: 0.2, 10, and 50 micron sized filters. These filters are used to fractionate samples to measure different sized algae. Each fractionated sample will be measured for fluorescence and the corrected fluorescence value calculated at the end of the analysis will represent the 10-50 micron sized algal cells.

    2-3 times with the 50 micron filtered sample before filling the glass cuvette with the filtrate. 6. Wipe the outside of the glass cuvette, insert the cuvette into the Ballast-Check 2 and close the sample compartment’s lid.

    Figure 1 2.6 Data Downloading The Ballast-Check 2 can log a total of 1000 data points that can be downloaded directly to your PC or computer using the provided serial cable. A terminal program (e.g. Hyperterminal, Terra Term, MotoCross) is required for downloading these stored ASCII data from the instrument.
  • Page 11 Confirm data are saved to your PC before proceeding to clear data from the Ballast-Check 2. The Ballast-Check 2’s memory starts at 100% for 1000 data points. If the memory is more than 90% full and the READ button is pressed, the following message will display: “Warning: Memory >...

  • Page 12: Sample Analysis Guidelines

    • Use the same cuvette for your samples, it is very important that you thoroughly rinse the cuvette between samples. The Ballast-Check 2 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.

  • Page 13: Measurement Parameters

    Measurement Parameters 4.1 Abundance - Corrected Fluorescence (CFI) The Ballast-Check 2 is configured for detecting fluorescence from chlorophyll in live algal cells (i.e. in vivo detection of Chlorophyll). Light from the fluorometer is absorbed by algal cells and fluorescence emitted by the cells is detected, quantified, and displayed as a digital number (CFl), estimating the abundance of algae in the sample.
