Abstract Investigations have definitely shown that the quantity of both chlorophyll types a and b can be nondestructively measured in solution by use of laser enhanced absorption spectroscopy (LEAS) at 1/100 the concentration easily detectable by use of ordinary spectrophotometric methods; this is a 100 times increase in sensitivity. It is estimated that the ultimate sensitivity for the LEAS technique is 10,000 times greater than that for ordinary spectrophotometric methods. (Modified author abstracts)
