Resetting the standard in LC autosampling
Spark Holland Product Profile
Packed with features, the IntegrityTM autosampler from leading supplier, Spark Holland, has been designed for optimum care of precious samples. Innovative sample barcode identification technology ensures better control of sample tracking – 1D and 2D sample and tray identification codes can be read, filed and linked to sample assay results. Injection performance monitoring verifies that the injection itself has been performed correctly. Integrity even checks for needle obstruction and missing vials before injecting a sample.
Spark’s concept of closed line sampling using pressure assisted sample aspiration 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 features advanced reagent addition and derivatisation, in addition to integrated online sample prep capabilities. With full software control, and compatible with UHPLC systems up to 120MPa (18,000 PSI), Integrity provides complete flexibility in LC autosampling capability.
Setting a new standard in sample care, the Integrity is the latest addition to Spark’s range of renowned autosamplers – Alias, Optimas and Reliance.

SPE-Based Method for Detecting Harmful Textile Residues
January 14th 2025University of Valencia scientists recently developed a method using solid-phase extraction (SPE) followed by high-performance liquid chromatography coupled to high-resolution mass spectrometry (HPLC–HRMS/MS) for detecting microplastics and other harmful substances in textiles.
The Complexity of Oligonucleotide Separations
January 9th 2025Peter Pellegrinelli, Applications Specialist at Advanced Materials Technology (AMT) explains the complexity of oligonucleotide separations due to the unique chemical properties of these molecules. Issues such as varying length, sequence complexity, and hydrophilic-hydrophobic characteristics make efficient separations difficult. Separation scientists are addressing these challenges by modifying mobile phase compositions, using varying ion-pairing reagents, and exploring alternative separation modes like HILIC and ion-exchange chromatography. Due to these complexities, AMT has introduced the HALO® OLIGO column, which offers high-resolution, fast separations through its innovative Fused-Core® technology and high pH stability. Alongside explaining the new column, Peter looks to the future of these separations and what is next to come.
