10 Fructosamine was estimated turbidimetrically
using Fortress kit, UK.
2-] content present in the water samples were analysed by turbidimetrically
at 450 nm using UV-spectrophotometer (SPECORD 40, Analytic Jena, Germany).
Instead of observing the formation of the fibrin thread, the clotting reaction was monitored turbidimetrically
by measuring the absorbance at 412 nm.
Sulfate concentration was determined turbidimetrically
(Rhoades 1982), and Fe concentration was determined by atomic adsorption spectrometer.
Algal stock concentrations were determined turbidimetrically
and translated to dry mass per unit volume using a previously determined dry mass regression.
Serum LP(a) was estimated by an immunoturbidimetric assay specific anti-lipoprotein (a) anti-bodies react with antigen in the sample to form antigen- antibody complex which is determined turbidimetrically
in a biochemistry analyser (RA-50 Bayer diagnostics) with "Quantia" Reagents kit.
2-]) was analysed turbidimetrically
using flow injection analysis colorimetry (Lachat QuikChem 8000).
Plasma cystatin C was measured turbidimetrically
(7) on a Hitachi 704 instrument, and creatinine was determined enzymatically (8) on the same instrument.
total] was determined turbidimetrically
(Specol 220, VEB Carl Zeiss Jena).
