Laboratory High Purity Reagents

Chromatographic Purity & Solvent Engineering

Modern liquid chromatography demands solvents with exceptional optical transmission and minimal organic contamination. As detection limits drop to the femtogram level, even microscopic impurities in the mobile phase can manifest as 'ghost peaks,' UV-absorbing artifacts, baseline drift, or ionization suppression in Mass Spectrometry. AIMRSE engineers its LC-MS and HPLC Grade Solvents through a proprietary multi-stage rectification process. We specifically target the removal of critical impurities such as phthalates, plasticizers, and homologous hydrocarbons that are often introduced during standard packaging processes.

Our Acetone, Acetonitrile, Methanol, and Water undergo Ultra-fine sub-micron filtration (0.1µm or 0.05µm available upon request) to remove particulate matter that could damage ultra-high pressure (UHPLC) pump seals and clog columns with sub-2-micron packings. By strictly controlling the acidity and alkalinity, we ensure that our solvents do not alter the retention times of ionizable analytes. Furthermore, our solvents are formulated to have low UV absorbance at critical cutoff wavelengths (e.g., < 0.005 AU at 200nm for Acetonitrile), creating a crystal-clear window for UV-Vis detection of low-concentration compounds.

Trace Elemental Analysis & Acids

In elemental spectroscopy (AAS, ICP-OES, ICP-MS), the acid matrix is the primary source of blank contamination. Standard reagent-grade acids often contain metallic impurities in the parts-per-million (ppm) range, which can completely mask the signal of trace elements in a sample. AIMRSE produces Trace Metal Grade and Ultra-Trace Grade acids via sub-boiling distillation in quartz and fluoropolymer apparatus. This slow, low-temperature distillation prevents the entrainment of aerosols containing heavy metal contaminants.

Our Nitric, Hydrochloric, and Sulfuric acids are tested for up to 65 metallic elements. For our Ultra-Trace line, we certify metal content in the parts-per-trillion (ppt) range. These reagents are packaged in pre-leached Teflon (PFA) or FEP bottles to prevent the leaching of sodium, calcium, and boron from borosilicate glass. This level of purity is essential for environmental monitoring, semiconductor wet processing, and geological isotope analysis where accuracy is non-negotiable.

Product Specification Matrix

Our reagents are categorized by application suitability, from general analytical use to ultra-sensitive instrumental analysis. Each batch is subjected to extensive QC testing including GC-FID, UV-Vis scanning, and ICP-MS.
