Resetting the standard in LC autosampling

Spark Holland product profile

Leading supplier, Spark Holland, has introduced the INTEGRITY™ autosampler – setting a new standard in sample care.

Packed with features, INTEGRITY™ has been designed for optimum care of precious samples. Innovative sample barcode identification (SBI™) technology ensures better control of sample tracking – 1D and 2D sample and sample tray identification codes can be read, filed and linked to sample assay results. It is even possible to record an image of the vial during sampling for visual verification of the injection and the sample vial afterwards. Combined with positive feedback motion control for the sample tray positioning, the risk of assigning results to the wrong sample is zero. Injection performance monitoring (IPM™) verifies that the injection itself has been performed correctly by pressure monitoring of the sample flow path during the entire injection cycle. INTEGRITY™ even checks for needle obstruction and missing vials before injecting a sample. Accurate sample temperature control is available from 4 - 40°C for the entire sample tray and sample processing space.

Spark’s concept of closed line sampling using pressure assisted sample aspiration (PASA™) directly from vial to valve has been specially developed for handling small samples, carryover and compatibility with UHPLC. A separate needle wash pump for better needle wash and faster injection cycles enable an entire injection-wash cycle in less than 20 seconds. Vial bottom detection facilitates efficient use of available sample volume and the microlitre-pick-up mode reduces sample loss to zero.

INTEGRITY™ is optimised for UHPLC systems up to 120MPa (18,000 PSI) and features advanced reagent addition and derivatisation, in addition to integrated online sample prep capabilities. The SparkLink™ software platform is available to provide comprehensive control of the extensive INTEGRITY™ capabilities. A special version of INTEGRITY™, the Integrity Plus doubles the standard 2 well plate capacity to accommodate 4 well plates or 216 standard 2ml vials.

Spark Holland will be showcasing the INTEGRITY™ at Pittcon (booth # 1161) or visit .
