Healing Power of Selenite
The selenite Crystal deposit was laid down over 250 million years ago in a complex array of interlocking, massive selenite crystals, the largest of which we have estimated to be in excess of four tons. The largest selenite crystal we have actually removed from the deposit weighs in excess of 4000 pounds.

Selenite Meaning & Healing Properties
The Selenite crystal meaning is highly effective for clearing and cleansing your energy, as well as the energy of your environment and even your other crystals. The Selenite crystal stone meaning is so effective because it has the ability to both remove lower vibrational energy and recharge whatever it is clearing with higher vibrations.

HILIC peak tailing
1) When the mobile phase is 75% ACN, then the sample solvent should contain at least 65% ACN, and preferably 70%. With the 50% ACN that your sample solvent contains, then at least some of the carnitine will migrate down the column faster than the rest of the carnitine until solvent exchange occurs. That produces tailing. 2) …

It is clear that the level of confidence in the liberation data for the lower grade sample from the tailing stream (Cu grade 0.11%) would be much less than the confidence in the higher grade concentrate sample (Cu grade 15.5%). The low grade nature of the tailing stream results in much lower numbers of particles of interest being present in ...
