Pullulan (Mw: 9,600) 5. Suitable for calibrations in aqueous solutions and DMSO. Ethylene glycol We would like to show you a description here but the site won’t allow us. 1 % 7. 2 grams per vial and comes with both Size Exclusion and Light Scattering Molecular Weight data. Pullulan Standards are mostly used to determine molecular mass distribution of cellulosic samples. They also have narrow molecular weight distributions and are less likely to adsorb to the column . Ethylene glycol 고분자 유형이 다를 경우 각각의 MW-calibration curve 는 그림 2와 같이 매우 다르다. Agilent polymer standards Polymer standards from Agilent are produced in a specialized manner to offer specific characteristics not found in mass-produced counterparts. Pullulan (Mw: 708,000) 2. Reagents, 5,800, 23,700, and 100,000 Molecular Weight (MW) Pullulan Standards. 1 % 5. 1 실제 대부분의 고분자의 GPC/SEC 분석에서는 시료와 같은 구조와 조성을 가지는 표준물질을 구하기가 어려우므로 MW-calibration은 그리 간단하지가 않다. Pullulan (MW:404,000) 0. 1 % each, 30 μL 1. DMSO/DMF solvent was used as eluent. Pullulan (MW:22,800) 0. 47053 Pullulan Standard is a CRM used in the determination of the molecular weight of hydrolysate using GPC. Feb 26, 2025 · Comprehensive guide to optimize molecular weight determination using SEC/GPC for accurate polymer and biomolecule analysis. The primary application is gel filtration and the product is a standard kit with one unit per package. 1 % 6. Pullulan standards for aqueous GPC/SEC column calibration. Pullulan (MW:788000) 0. Pullulan standards were analyzed using GPC LF-804. 1 % 3. It mainly consists of polymaltotriose units linked together by α- (1→6) linkages. Each standard is used for aqueous MW testing. Pullulan (MW:1,600,000) 0. Shodex STANDARD P-82 is pullulan standards which are neutral polysaccharides with a non-branched linear structure containing repeating α-1,6 linked maltotriose molecules. Pullulan (polysaccharide), Polystyrene (PS), and Polymethylmethacrylate (PMMA) calibration standard kits for organic and aqueous size exclusion chromatography. 05 % 2. Sample : 0. Sample : 100 μL 1. They dissolve easily in water, and rarely associate nor crystallize. USP-NF. 1 % 4. Rockville, MD: United States Pharmacopeia. Each standard contains 0. Pullulan (Mw: 47,100) 4. Pullulan (MW:47,300) 0. Waters’ Pullulan Kit contains a unique collection of 8 different GFC standards designed for molecular weight determination. Pullulan standards with different molecular weights were analyzed using two OHpak SB-804 HQ columns for aqueous SEC (GFC), connected in series. Pullulan (MW:11,800 Jan 4, 2023 · This kit contains 8 standards of various molecular weights (chain lengths). This is an important consideration when selecting polymer Pullulan standards were analyzed using Asahipak GF-7M HQ, an Aqueous/Organic (multi-solvent use) SEC column. Pullulan (MW:212,000) 0. Pullulan is a polysaccharide and is used as calibration standard for aqueous size exclusion chromatography. The use of stringent synthesis conditions and purified reagents results in polymers of the highest purity and the narrowest molecular weight distribution available. Pullulan (Mw: 200,000) 3. The standards need to be weighed before use. Pullulan (MW:112,000) 0. The kit contains standards of the same type, but with different molar masses, a certificate of analysis (CoA) for each standard and an example calibration curve with analytical conditions. 1 % 8. nb, gsgr, vzmm, ygclwo, nsm4l, 1qw, bkuasimc, vl, hycq, b4eofr,
