Application Notes: General

A novel HIC column featuring innovative particle technology is benchmarked for separation of high DAR species ADCs, against a reference column with conventional chemistry.

Cells beyond their sell-by date exhibit a higher probability to propagate damaged cellular components like DNA, which leads to disease. It is therefore necessary for the body to remove these old malfunctioning cells, which can be done with garlic. All of the active components of garlic are easily isolated using the 5 µm PRP-C18 HPLC column.

Capsaicin, the compound responsible for the burning sensation in chili peppers, has been researched for its potential therapeutic benefits, including reducing cholesterol and blood sugar levels, and exhibiting anti-inflammatory and analgesic properties. Hamilton's PRP-C18 reversed-phase HPLC column was used to isolate major capsaicinoids, with formic acid as the aqueous mobile phase, achieving good correlation with literature values at 10190 Scoville Heat Units. The Hamilton PRP-C18 column demonstrated excellent peak shape and can be easily regenerated, making it an indispensable tool for synthetic chemists.

In this study of an essential oil, we have developed an HPLC method for the separation of 6 well-known markers for the determination of purity of Ylang-Ylang oil.

Due to the short half-life of the 18F radionuclide, radiotracers are preferably produced locally or transported over short distances, leading to local production. On-site quality control is critical before clinical use. See how the RCX-10 enables reliable analysis for radiotracers.

This study analyzed BPA and its derivatives leaching from BPA-free polycarbonate water bottles using HPLC with UV detection and found that these bottles still contain bisphenol derivatives that can leach into water or ethanol. Leaching increased with temperature and was more pronounced with ethanol than hot water. Repeated washing with either hot water or 40% ethanol effectively removed leachable bisphenols without damaging the bottles.

Metrohm’s MiPCT-ME technique enables trace-level determination of anions in N-methylpyrrolidone, ensuring lithium-ion battery quality, stability, and safety.

This method showcases a precise, automated workflow for determining methylene chloride in indoor air using thermal desorption GC-MS and GERSTEL’s ISDP module. Automated gaseous internal standard addition ensures highly reproducible tube spiking, while optimized TD and GC-MS parameters provide sensitive and stable quantification—well below OSHA exposure limits. The approach enables accurate baseline monitoring in laboratories, offices, and industrial environments where regulatory compliance and worker protection are essential.

The GERSTEL TVOC Wizard streamlines and accelerates VDA 278 material emissions data processing by combining automated workflows, advanced deconvolution, and integrated NIST-based compound identification. Complex chromatograms—often dominated by co-eluting peaks—are reliably resolved using MCR-AR Targeted algorithms, while retention indices and customizable process steps ensure standard-compliant, high-quality results. The software eliminates error-prone manual transfers, increases data consistency, and delivers clear, customizable VOC and FOG reports aligned with industry requirements.
