Webthe SDSS photometric system. Using this catalog, we show that photometric zeropoints for SDSS observing runs can be calibrated within nominal uncertainty of 2% even for data obtained through 1 mag thick clouds, and demonstrate the existence of He and H white dwarf sequences using photometric data alone. WebISE system is used in the quantitation of sodium, potassium and chloride. The photometric system can measure colorimetric or nephelometric reactions utilizing end point or kinetic (rate) absorbance measurements. Test ordering on the Cobas 6000 and resulting in the Misys host computer system may be done manually or
