For general use, the Waters Alliance e2695 is highly recommended, while for high-temperature applications, the Agilent 1260 Infinity II is ideal.<\/li>\n<li><strong>How much does a GPC instrument cost in 2026?<\/strong> Prices range from $10,000 for entry-level Chinese models to $100,000 for advanced multi-detector systems from international brands.<\/li>\n<li><strong>Where can I buy a used GPC system?<\/strong> Check platforms like LabX, EquipNet, and eBay, or contact refurbished instrument dealers such as Conquer Scientific.<\/li>\n<li><strong>What is the difference between GPC and HPLC?<\/strong> GPC separates by size, while HPLC separates by polarity. GPC is used for polymers; HPLC for small molecules.<\/li>\n<li><strong>Can GPC measure absolute molecular weight?<\/strong> Yes, when coupled with light scattering or viscometer detectors, GPC can determine absolute molecular weight without calibration.<\/li>\n<li><strong>What solvents are used in GPC?<\/strong> Common solvents include THF, chloroform, toluene, and water (for aqueous GPC). The choice depends on polymer solubility.<\/li>\n<li><strong>How do I maintain a GPC column?<\/strong> Flush columns with pure solvent, avoid high pressure, and store columns in appropriate solvent. Replace columns after 500-1000 runs.<\/li>\n<li><strong>What is the typical accuracy of GPC?<\/strong> GPC accuracy is within 5-10% for molecular weight averages, depending on calibration and detector quality.<\/li>\n<li><strong>Is GPC suitable for biopolymers?<\/strong> Yes, aqueous GPC with biocompatible columns is used for proteins, polysaccharides, and nucleic acids.<\/li>\n<li><strong>How long does it take to learn GPC?<\/strong> Basic operation can be learned in 1-2 days, but advanced data interpretation may require weeks of practice.<\/li>\n<\/ol>\n<h2 id=\"toc-63bcedea8f6d6e482d12e23d840e8ab1\">Dados aduaneiros e taxas pautais<\/h2>\n<p>GPC instruments fall under HS Code 9027.20 (Instruments for physical or chemical analysis).
