分析實例

不需衍生化同步分析含醛物質

Chromatogram of Aldehydes in Water

硫化物同步分析

Chromatogram of Gas Mixed with Sulfur
Compounds at 1 ppm (balanced with He)

TCD的100 倍以上靈敏度，FID的2-3倍以上的靈敏度

以往需使用數臺檢測器才能同時分析無機氣體與低碳氫化合物，現在利用BID，選擇合適的分離管柱，即可同時測得無機氣體與低碳數碳氫化合物且高感度的分析資料。

各成分5 ppm in He、分流分析1:5、取樣量1 mL

BID與FID的靈敏度比較

利用BID，在FID下靈敏度較差的醛、醇與鹵烷類的分析靈敏度可得到大幅度提高。

各成分10 ppm in 甲醇、分流分析1:29、取樣量1 µL
