摘　　要：在紫外和示差折光检测器双通道检测和示差单一检测器条件下,对秸秆蒸汽爆破处理液中糖、酸和醛三大类物质的测量精度进行了比较,结果表明双通道检测中对醛类物质有更高的检测限。在两种检测条件下,对水解液5、20倍稀释液的成分的测量结果进行统计学分析,结果表明无显著性差异,表明检测限在单一检测器的影响在所测浓度范围内可以消除,证明示差单一检测器条件下完全可对秸秆蒸汽爆破处理液进行分析检测。Sugar, acid and aldehyde in liquid phase obtained from corn straw steam explosion pretreatment was analyzed by high performance liquid chromatography (HPLC) equipped with UV and RID detectors. Compared with single RID detector, the HPLC system with UV and RID dual-channel detectors has higher detection limit to aldehyde. Statistical analysis to measurement results of 5 or 20-fold dilution of the hydrolysate showed that there was no significant difference, indicating that the impact of detection limit can be...
