Our column's performance speaks for itself. Other silica columns promise per formance...our columns deliver. And speaking of delivery, you'll be im pressed by our response to your needs. In most cases, our vitreous silica col umns will be on the way in less than 24 hours after your order is received. And when you order, subtract the price of our columns from the competition's and put the difference in the bank. SGE FLEXIBLE VITREOUS SILICA CAPILLARY COLUMNS give you more performance in less time for fewer dollars. To order FLEXIBLE VITREOUS CAPILLARY COLUMNS consult your SGE CHROMATOGRAPHY AND MASS SPECTROMETRY CATALOG or contact your SGE Distributor.

Realize the full potential of your amino acid analyzer with • Pickering reagents. Now you can get a complete family of reagents for amino acid analysis (protein hydrolysates) from Pickering Laboratories— the same company that brought you Trione™ the ready-to-use ninhydrin reagent recommended by amino-acid analyzer manufacturers. Our reagents include sodium eluents (pH 3.28,4.25, and 7.40), régénérant, diluent, chromatographic grade o-Phthalalde-
hyde (ΟΡΑ), and ΟΡΑ diluent. All Pickering eluents offer you superior pH stability (±0.01), controlled normality, and the lowest amine contamination on the market. Our ΟΡΑ and Trione post-column reagents let you detect concentrations of 100 picomoles or less. These reagents are available now, and will be shipped the same day we receive your order. Call or write us today.
