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.

Chroma3-Case-cut-out

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%

Method comparison: High-performance liquid chromatography (HPLC)
