薄层扫描仪是用于进行薄层扫描定量分析的仪器。虽然它的操作方法、设备等在其30多年的历史中已有许多改进,但整个应用过程是不连续的,且较为复杂,每个操作步骤都会影响定量的准确性。因此,它的使用范围受到一定限制。相比之下,分光光度计的使用要简单得多,它可对液体样品直接分析,具有较好的分析灵敏度和精密度,可测元素较多,操作快速简单。鉴于薄层扫描仪与UV/VIS分光光度 TLC scanner is used for thin layer scanning quantitative analysis of the instrument. Although its methods of operation, equipment, etc., have many improvements over more than 30 years of its history, the entire application process is discontinuous and complex, with each step of operation affecting the quantitative accuracy. Therefore, its use is subject to certain restrictions. In contrast, the use of spectrophotometer is much simpler, it can be a direct analysis of liquid samples, with better analytical sensitivity and precision, measurable elements more, the operation is quick and easy. Given the TLC scanner with UV / VIS spectrophotometry
