Chromatography
Delivering reproducible solutions for chromatography sample preparation
Sample preparation is a critical step for chromatography to ensure samples are optimised for analysis. This step involves various techniques such as, solid phase extraction (SPE), phospholipid removal (PLR) or protein precipitation. Without proper sample preparation, chromatographic performance can be compromised, leading to inaccurate and irreproducible data.
Porvair Sciences’ comprehensive range of products for sample preparation includes a wide selection of consumables, such as the Microlute® range, sample collection plates, and vials. Additionally, the company provides instruments such as the Ultravap® evaporators, vacuum manifold and UltraPPM LITE positive pressure manifold to ensure optimal sample preparation.
The sample preparation product range includes: Microlute® CSi for silica solid phase extraction (SPE); Microlute® PLR for phospholipid removal; Microlute® PPP for protein precipitation; Microlute® SLE for supported liquid extraction; Ultraseal™ range of adhesive and heat sealers for sample protection and storage; Ultravap® range of blowdown evaporators for sample concentration; UltraPPM LITE for positive pressure processing;Deep well microplates for sample collection, handling and storage.

FlowChrom by Testa Analytical is an automated, non-invasive system designed to continuously monitor and document HPLC system performance in real time.
While HPLC and UHPLC systems are designed for round-the-clock operation, issues can arise when systems are left unattended, often making it difficult to pinpoint the source and timing of problems. Among the most common challenges is solvent delivery system malfunction, highlighting the need for continuous monitoring.
FlowChrom addresses this need by seamlessly integrating with most chromatography data systems (CDS) to provide a digital safety net. It creates a reliable, traceable record of HPLC solvent delivery system performance, flagging any deviations and confirming the validity of every separation.
This real-time tracking not only simplifies troubleshooting but also creates a comprehensive digital archive of HPLC operational data, especially valuable in regulated environments. Additionally, FlowChrom allows scientists and technicians to focus on more productive tasks, reducing the burden of constant monitoring.

Solvent recycler drives sustainability in pharma labs
Revolutionising HPLC: New LC Series offers advanced automation and sustainability
Agilent Technologies has unveiled its next-generation Agilent InfinityLab LC Series, comprising the 1290 Infinity III LC, 1260 Infinity III Prime LC, and 1260 Infinity III LC systems, including biocompatible options. These systems are the first to feature the new Agilent InfinityLab Assist Technology, designed to streamline lab operations with advanced automation and system assistance.
The InfinityLab Assist helps optimise tasks by automating instrument routines, simplifying sample preparation, and assisting with maintenance and troubleshooting. The inclusion of barcoding and camera technologies enhances sample tracking and reduces the likelihood of errors, improving accuracy and efficiency.
With this launch, Agilent aims to improve lab productivity by minimising manual operations and reducing operator training time. InfinityLab Assist technology provides real-time insights into system health, assisting analysts at all levels in achieving faster, more reliable results.
The new systems are also compatible with previous LC models and integrate seamlessly with chromatography data systems (CDS). Verified by the ACT 2.0 Ecolabel, these systems prioritise sustainability, being the first LC systems to provide users with a CO2 footprint analysis.
Philip Binns, President of Agilent’s Life Sciences and Applied Markets group, highlighted that this new series sets a benchmark in liquid chromatography, offering a robust solution for labs looking for enhanced automation, precision, and sustainability.
The Infinity III LC Series will be launched globally in October 2024 at major scientific events including HPLC 2024 in China, PharmSci 360 in the US, and the HUPO World Congress in Germany.

Biotech Fluidics has announced that a leading pharmaceutical company has invested in 17 SPR-200 solvent recycler units to enhance the sustainable use of solvents in HPLC systems across its analytical laboratories.
The SPR-200 operates as a standalone, externally powered unit, eliminating the need for an external computer and avoiding potential connectivity challenges with IT systems.
Designed for compatibility with most HPLC systems, the SPR-200 continuously monitors detector output signals during liquid chromatography. In customer laboratories, it has demonstrated the ability to recover up to 90% of the mobile phase by redirecting purified solvent into a dedicated reservoir during isocratic HPLC.
Fritiof Ponten, CEO of Biotech Fluidics, commented: “Controlled via an integral LED screen and membrane keyboard – the SPR-200’s user-friendly software allows you to configure operational parameters and to perform online monitoring and create an audit trail of recovered solvent.”
He added: “Not only does the SPR-200 improve sustainability in your lab, but it also quickly pays for itself by enabling you to recycle nearly all the solvent used in your isocratic HPLC systems.”
