PE,

Do spectrophotometers have a ability to create different temperature lights in to starch grains or do we need a light source ?
Does China produce these test devices , what size do they come with ? What is the cheapest ones price ?
I am receiving dye quatations from china and most expensive one 1 gram / 10 dollars range to 25 cent range for Autochrome.
Still waiting the monday.
