HPLC Columns

TSKgel UP-SW3000-LS

The TSKgel UP-SW3000-LS columns are dedicated to U/HPLC size exclusion analyses of monoclonal antibodies and other biopharmaceuticals combined with advanced detection such as multi-angle light scattering (MALS) or mass spectrometry (MS). The 2 µm silica particles are diol bonded for a hydrophilic surface. This, in combination with its 25 nm pore size, make the columns optimally suited for the analysis of proteins ranging between 10 kDa – 500 kDa.

The key feature TSKgel UP-SW3000-LS U/HPLC columns offer is a low noise level when coupled with advanced detectors. This will save time for equilibration and improve data quality. For multi-angle light scattering (MALS) applications, a low noise level is achieved in minutes, leading to high signal-to-noise ratios and thus high sensitivity. For mass spectrometry applications, ionization efficiency by electrospray ionization is improved and increases overall MS performance and instrument uptime. This makes the TSKgel UP-SW3000-LS column ideal for in-depth analyses of aggregates and fragments of mAbs, bi- and multi-specifics.

Lot-to-lot reproducibility


Column: TSKgel UP-SW3000-LS, 2 µm,
4.6 mm ID × 30 cm of three different
production lots
Mobile phase: 100 mmol/L phosphate buffer, pH 6.7 +
100 mmol/L Na2SO4
Flow rate: 0.35 mL/min
Detection: UV @ 280 nm
Injection vol.: 10 µL
Samples: Protein standard containing thyroglobulin, gamma-globulin, ovalbumin, ribonuclease A, p-amino benzoic acid, 137 Da

TSKgel UP-SW3000-LS columns offer superior reproducibility injection-to-injection, from column-to-column within the same lot and from lot-to-lot. %RSD values for peak parameters including retention times, area peak height, peak asymmetry, and theoretical plate count demonstrate the exceptional reproducibility of these columns.
