ชุดทดสอบความขุ่น Standard Test (1 – 100 FAU)

NANOCOLOR® Turbidity (Formazine/DIN) Photometrische Bestimmung von Trübungen The turbidity of the pure sample is measured photometrically. NANOCOLOR® photometers are programmed with all necessary calibration date to express turbidity as the spectral absorbance coefficient 1/m or in internationally valid Formazine Attenuation Units (FAU) which are based on formazine standard suspensions.

ชุดทดสอบDetergents, anionic Standard Test (0.1 – 5.0 mg/l MBAS)

NANOCOLOR® Detergents, anionic Photometric determination of anionic detergents Photometric determination with methylene blue. Under suitable conditions anionic detergents react with methylene blue to form a coloured complex, which is extracted with an organic phase. Read More »

ชุดทดสอบสี Standard Test (5 – 500 mg/l Pt and 0.2 – 20 1/m)

NANOCOLOR® Colour Photometric determination of colours For determination of the colour intensity one uses the HAZEN scale, which is calibrated with platinum-cobalt chloride standards. In accordance with DIN EN ISO 7887-C1-3 the colouration is measured as spectral absorption coefficient at 3 wavelengths: ~436 nm, ~525 nm, ~620 nm. Read More »
