ABSTRACT:
Images comprised of silver such as X-rays and electrophoresis gel bands, wherein the size and darkness of the image provides useful information, are quantitated utilizing a spectrophotometer to quantify the silver which comprises the image. An image is isolated from X-ray film or an electrophoresis gel followed by removal therefrom of any silver which is present. The removed silver is complexed to cause an optical change. A spectrophotomer is then used to measure the absorbance and the absorbance measurement is compared with a calibrated reference standard.
