Waters, 186009969, MaxPeak Premier Protein SEC Guard, 250 Å, 2.5 µm, 4.6 x 30 mm, 1/pk

MaxPeak Premier Protein SEC Guard, 250 Å, 2.5 µm, 4.6 x 30 mm Guard Columns were developed to help scientists extend the column life of either an ACQUITY Premier Protein SEC 250Å, 1.7µm Column or an XBridge Premier Protein SEC 250Å, 2.5 µm Column without degrading desired separated component resolution. The useful lifetime of the guard column can be influenced by many factors including mobile phase cleanliness/microbial contaminatio , presence of sample precipitates/aggregates, working at extremes of pressure, pH, and/or temperature. Guard columns may need replacement if significant increase in column pressure is observed or if one sees wide tailing or split peaks. This guard column is compatible with: p/n: 186009959 XBridge Premier Protein SEC Column, 250Å, 2.5 µm, 4.6 x 150 mm p/n: 186009960 XBridge Premier Protein SEC Column, 250Å, 2.5 µm, 4.6 x 300 mm p/n: 186009961 XBridge Premier Protein SEC Column, 250Å, 2.5 µm, 7.8 x 150 mm p/n: 186009962 XBridge Premier Protein SEC Column, 250Å, 2.5 µm, 7.8 x 300 mm p/n: 186009963 ACQUITY Premier Protein SEC Column, 250Å, 1.7 µm, 4.6 x 150 mm p/n: 186009964 ACQUITY Premier Protein SEC Column, 250Å, 1.7 µm, 4.6 x 300 mm p/n: 176005067 XBridge Premier Protein SEC Column, 250Å, 2.5 µm, 4.6 x 150 mm w/ Standard p/n: 176005068 XBridge Premier Protein SEC Column, 250Å, 2.5 µm, 4.6 x 300 mm w/ Standard p/n: 176005069 XBridge Premier Protein SEC Column, 250Å, 2.5 µm, 7.8 x 150 mm w/ Standard p/n: 176005070 XBridge Premier Protein SEC Column, 250Å, 2.5 µm, 7.8 x 300 mm w/ Standard p/n: 176005071 ACQUITY Premier Protein SEC Column, 250Å, 1.7 µm, 4.6 x 150 mm w/ Standard p/n: 176005072 ACQUITY Premier Protein SEC Column, 250Å, 1.7 µm, 4.6 x 300 mm w/ Standard
