常见问题

NIR检测需要多长时间？

NIR检测通常需要7-15个工作日，具体时间取决于样品的物理形态、需要建立的定标模型复杂度以及单个样品的光谱扫描采集时间。若为已有成熟模型的常规批量样品，检测周期可缩短至5个工作日内完成。

NIR检测费用大概多少？

NIR检测费用根据检测项目数量确定，单项常规成分的光谱扫描与模型预测分析费用通常在数百元区间。若涉及新模型的建立、方法学验证或大量样本的批量筛查，需根据具体样品基质和测试方案单独核算费用。

NIR无损检测对样品有什么特殊要求？

样品需具备一定的代表性且表面平整以保证光路接触良好。固体样品通常要求无严重污染或表面反光，液体样品需澄清透明无气泡，浆体样品需质地均匀。对于温度敏感型样品，扫描前需恒温处理以消除温度对光谱基线的干扰。
