David L. VanderHart, Lane C. Sander, Xiaohong Gu, Tinh Nguyen, Stephen A. Wise, M Pursch, D A. Gajewski
C30 self-assembled monolayers (SAMs) have been prepared on zirconia, titania and two different silica gels by reacting C30 trichlorosilane with the humidified surfaces. 13 deg C solid-state NMR spectroscopy indicated higher alkyl chain order on titania and

Standard Reference Materials (SRMs) are certified reference materials (CRMs) issued by NIST that are well-characterized using state-of-the-art measurement methods and/or techniques for the determination of chemical compositon and physical properties. SRMs

Capillary Electrophoretic Determination of Oxalate in Amniotic Fluid

April 20, 1999

B C. Nelson, G F. Rockwell, T Campfield, P O'Grady, R M. Hernandez, Stephen Wise
A capillary electrophoretic (CE) assay for oxalate has been applied to the quantitative determination of free oxalate in amniotic fluid. Indirect absorbance detection of oxalate is accomplished with a chromate-based background electrolyte modified with
