Chlorophyll-a concentration in µg L\(^{-1}\) (assuming a 1 cm path
length and standard extraction volume).
Arguments
wl_630
Absorbance at 630 nm.
wl_647
Absorbance at 647 nm.
wl_664
Absorbance at 664 nm.
wl_750
Absorbance at 750 nm (turbidity blank).
Details
Absorbance values should be measured in a 1 cm path-length cuvette.
The 750 nm reading is used as a turbidity blank correction.
Formula: \(11.85 \times E_{664} - 1.54 \times E_{647} - 0.08 \times E_{630}\)
where \(E_{\lambda} = A_{\lambda} - A_{750}\).
