对于食品检测、环境和毒理学实验室中从事痕量分析工作的分析人员，可将我们专有的气相沉积 UltiMetal Plus* 应用于惰性焊件。如果要增加进样量来进行痕量分析，那么对流路中的热金属表面进行脱活处理很重要，因为样品将溢出衬管，分析物将暴露于金属表面中。
*请注意，脱活处理产生的颜色差异是正常的。

Split Inlet Troubleshooting
Split inlets are spared from most band-broadening phenomena, since the splitting process generates narrow peaks. Peak broadening or tailing is usually due to:
• Improper column installation
• Low inlet temperature
• Low split flow (<20 mL/min on 6890)
• Inlet and needle discrimination and decomposition
如果您的结果不准确或者不一致：
• Check the column and reinstall if necessary
• Increase inlet temperature by 50°C and compare results
• Check inlets and needles for wear and replace as necessary
不分流进样口故障排除
Most problems encountered with a splitless injection are related to:
• Incorrect purge time
• Degradation
• Improper focusing
• Inappropriate column temperature
• Backflash
You can also improve the reproducibility and linearity of peak areas and avoid backflash by matching:
• Inlet temperature
• Liner volume
• Injection volume
