🧪 EPA Method 8260 VOCs (Split Ratio 10:1-100:1, Splitless Hold Time 0.5-1.0 min, Siltek Liner)

GC-MS Split/Splitless Inlet Calculator

Optimize gas chromatography split and splitless inlet parameters for trace volatile organic compounds (VOCs) and semi-volatiles under EPA Method 8260 & 8270: calculate split ratio (10:1 to 100:1), calculate splitless hold time (0.5 to 1.0 min), size deactivated single-gooseneck wool liners (ul expansion volume), and environmental lab yields.
