Sunglasses Protection

Using absorbance spectroscopy measures, sunglasses effectiveness can be measured with OPS solid sampler, identifying sunglasses effectiveness and differences between quality of sunglasses for protection.

Sunscreen UV Protection

Absorbance spectroscopy sunscreen effectiveness measurements at different dilutions with the Open Platform System (OPS) answers when sunscreen effectiveness ends and why we must reapply sunscreen.

Open Platform System Educational Applications with Chlorophyll

Professor Apblett from Oklahoma State University provides educational applications for undergraduate laboratories and analytical chemistry using our Open Platform System for chlorophyll measurements.

Chlorophyll in Leafy Vegetables

Our Open Platform System can measure the presence of Chlorophyll in various leaves via liquid extract or solid leaf sample. Our measurements were performed on the leaves of Spinach, Rhubarb, Beetroot, and Parsley, as seen below.

Riboflavin in Milk

The Open Platform System can be used to easily measure organic liquid samples. The presence of Riboflavin in various milk samples were measured using our 365 nm light source.
