内标法和外标法是分析化学中常用的两种定量分析方法。
内标法将已知量的内标物质加入到样品中，该内标物与待测物质理化性质相似，又能够被分析仪器区分。内标物在分析过程中与待测物一同经历样品前处理步骤，包括提取、稀释、衍生化等，最终通过测定内标物和待测组分的峰面积或峰高及其相对响应值来计算待测组分含量。
外标法则是通过制备一系列已知浓度的标准溶液，绘制标准曲线，根据待测样品的响应信号与标准曲线比对，从而计算待测样品的浓度。
内标法的核心优势之一是它能够显著提高分析的准确度。通过比较内标物和被测物的响应信号，可以纠正分析过程中的任何偏差，包括样品处理、提取、转换和检测过程中的误差。选择合适的内标物质是内标法成功的关键，内标物质应当与被测物有相似的物理化学性质，以保证在分析过程中行为一致。
百灵威全新推出一系列氘代内标物，涉及食品、环境、农兽药、抗生素、医药等多个领域，产品同位素丰度高，定值准确。
