Solid Phase Extraction Column

NAVIGATORThe series of products have high quality and performance in chromatographic analysis. Widely used for extracting target analytes from various complex matrices, such as biological fluids (blood and urine), water samples, soil, food, etc., to achieve concentration or purification before chromatographic analysis.

NAVIGATORThe solid-phase extraction column is filled with high-purity spherical adsorbents, which are distributed more evenly, ensuring the repeatability and reliability of experimental results, in order to ensure a safe, reliable, and efficient sample preparation process.

NAVIGATOR C18E

• C18Fixed phase is the most hydrophobic silica gel based adsorbent, which has excellent retention properties for non-polar compounds and retains most organic compounds. It is currently the most widely used photoluminescent adsorbentSPEAdsorbent. Due toC18Most organic substances in water-soluble matrices have retention capacity, resulting in low selectivity, and are often used to treat analytical samples with multiple structures or significant structural differences. At the same time, due toC18EThe filler does not retain salt * and can usually be usedC18ESmall columns replace ion exchange columns for desalination of some small molecules and some medium-sized molecules.NAVIGATOR C18EThe carbon load of the product is17%.

NAVIGATOR C18E HC

• C18Fixed phase,C18E HCCompared to the standardC18EAdsorbents have similar properties, but with a higher carbon loading capacity, reaching up to25%Such high carbon loading fillers further enhance the retention ability of weakly polar compounds.

NAVIGATOR C18

• C18The extraction column, with more residual silanol groups on the surface, provides extra polar interactions, making the hydrophobic bonded silica gel more tightly connected to the highly polar extract, enhancing its ability to retain alkaline compounds and polar substances. Compared to the sealed tailC18EIt is a universal stationary phase for extracting polar and non-polar compounds.NAVIGATOR C18The carbon carrying capacity is approximately24%The performance is equivalent toBondElute C18 OH.
