iCheck Chroma 3 and Test Kit For Vitamin A in Edible Oil Analyzer
iCheck Chroma 3 Measures Vitamin A in Edible Oil
iCheck Chroma 3™ is a state-of-the-art portable photometer for measuring vitamin A concentration in edible oil. The iCheck is specifically developed and equipped with innovative technology to enable technically sophisticated measurement of absorption. iCheck Chroma™ 3 displays vitamin A concentration in mg RE/kg and IU/g.
Analyte: Vitamin A (retinol) as retinyl palmitate
Sample: Refined edible oils: palm, soy, cottonseed, sunflower, corn, peanut, rapeseed, coconut, rice bran
Sample preparation: If the oil is solid, warm it up to a maximum of 50°C to make it liquid
Sample volume per analysis: 0.1 mL (100μL)
Concentration range: >3.0 ppm (mg/kg), samples above 30.0 ppm must be diluted in refined unfortified oil
Analytical method: Photometric determination of retinol concentration using colorimetric Carr-Price reaction combined with compensation for matrix effect
Units displayed: mg RE/kg and IU/g; RE – retinol equivalents, IU – international units
Linear range: 3.00 – 30.00 mg RE/kg (10.00 – 100.00 IU/g)
Calibration: Factory set (standards included for control)
Time per analysis: < 2 min
Environment: 20 –30°C, no direct sunlight
Accuracy at 95% confidence interval at 25°C: <±30%
