The higher Guz evsileble in the NES reactor permita the detection cf elerzints at elgnivicantly lower levels as which might be anticipated in c-inute sem ples of textile fibers. As you know. there are verious techniques for determinetion of density, some of which are cumbersome and time-consuming. We are equipped to make specific determinntions of density with a rapid and relistle technique. Again, we would be pleased te make thie equipment wvallsble our Leboratery. It should be noted that this is 4 dunsity determinaticn technique and net simply 8 comparative density test. I hope you will not hesitate to call on this Leburetory to discuss thesa anrlytical probler:s or any others which may arise, Bo sesured that cur intcrest is not to supplant but merely support end enhance, where possidle, the ferensic examinstion services being performed in your Ieboratory.
