Example – LTM II GC Driver UI
GC oven screen i thremains the same
except for the addition of the LTM tabs
The number of tabs will equal the number of LTM’s installed,

LTM II1. high throughput (not too complex sample)
• TPH/HOI analysis contract labsSIMDIST• SIMDIST
• residual solvents2. Researchers interested in multidimensional GC
• Deans switch needs LTM (or two ovens)• GCxGC with second dimension temperature offset
3 “S i l fi ti ”3. “Special configurations”In a world of emerging MS technologies, the importance of the (GC) separation should not be underestimated: better separation, backflushing,heart-cutting, etc…improves MS data quality,
even with QQQ or QTOF instruments
Environmental – TPH - Total Petroleum HydrocarbonNeed for high through-put, especially for low margin samples like TPH, where analytical cycle times are a critical element in making a profit Key Sales Toolsy
