GuardGOLD™ Capillary Columns (Thermo Scientific™)

Protect your analytical column from damage and contamination from nonvolatile materials using the ThermoScientific™ GuardGOLD™ Capillary columns.Facilitates Superior Analytic Performance Protects against column contamination caused by nonvolatile materials, extending the column lifetimeFocuses target analytes at the head of the analytical column, leading to better chromatographic peak shapeHighly deactivated to provide superior inertness, essential for analysis of active compoundsHigh maximum operating temperature of 360°C

Key Features

Ideal for High-Throughput, High-Resolution LC

The UltiMate 3000 Rapid Separation Well Plate Autosampler is strongly recommended for high-pressure, high-resolution applications. Short injection cycle times make it ideal for high-throughput applications. It is available in both nonthermostatted (WPS-3000RS) and thermostatted (WPS-3000TRS) versions.

Performance and Features

Injection volume precision typically <0.15% RSD for 5μL injections
High-precision drive mechanism to deliver superior injection linearity of r2 >0.9999 (5–90μL)
Wide injection volume range from 0.2 to 500μL using three syringe and loop combinations for maximum injection flexibility
Low gradient delay volume of 140μL (default) or 50μL (with 25μL sample loop)
Volumetric accuracy better than ±0.5% for 20μL injections allow easy method transfer from HPLC to UHPLC
Sample thermostatting to protect thermally-sensitive analytes (WPS-3000TRS)
