Consistent average particle size and particle size distribution assure consistent interaction efficiencies and optimum flow rates. High surface area allows maximum capacity. Consistent elemental analysis. This key parameter assures uniform surface characteristics and performance. Uniform, high titer (as appropriate) controls ligand density of the bonded phase for consistent selectivity and capacity. Effective endcapping (as appropriate) assures minimal silanol interaction on endcapped (reversed phase) sorbents. Surface characterization tests with molecular probes control extraction selectivity and assure consistent performance. pH control of column eluant verifies proper washing of the bonded phase and freedom from interference. Minimum turbidity assures silica fines and other extradables have been removed during manufacture. Color of methanol eluant controls soluble extractables. Minimum residue assures freedom from extractable impurities. Actual use test (as applicable): BAKERBOND spe columns manufactured for specific applications are tested in that application. The test assures high consistent recovery of the analyte(s) without interfering contaminants.
One of the major concerns with solid phase extraction has been reproducibility. Here's how J.T.Baker has solved it. And a Report of Analysis to prove it. Today's solid phase extraction columns from J.T.Baker are the state of the art. To assure you accurate, reproducible solid phase sample preparation, J.T.Baker has developed some of the industry's most advanced technology and meaningful test result information: • State-of-the-art bonded phase (batch sizes up to 150 Kg) and BAKERBOND spe* column manufacturing techniques—to
give you consistent sample preparation performance and reliable delivery. Solid phase extraction products manufactured using Statistical Quality Control (SQC) and Statistical Process Control (SPC)—to assure you that key parameters are consistently held within narrow limits for minimum lot-to-lot variation.
