Most GRO-like methods require a purge and trap technique for sample introduction into the GC. US EPA Method 8015 also allows direct injection to be used in some instances (such as for high level samples). Figure 2 shows a chromatogram of our EPA GRO Mix. An SLB™-5ms column with a 1.0 μM film was used to help focus and retain 2-methylpentane.

InSitu GOR measurement determines the gas/oil ratio (GOR) and condensate/gas ratio (CGR) downhole and in real time from vaporizations of the hydrocarbon and CO2 components at standard conditions for flashing a live fluid.

Grodan. Since switching to the new Improved Gro-Blocks, we’ve noticed a significant di. ference. We’re getting healthy root acceleration all the way through, even block saturation from top to bottom, and they react great to dry .

Grodan Improved Gro-Slabs and Uni-Slabs offer a wide control range to steer your crop using irrigation strategies. Featuring the Advanced Wetting Agent, Gro-Slabs offer more uniform WC and EC distribution throughout each slab and from slab to slab.

GyroLink service reduces the risk of stuck pipe, assists with relief-well drilling, and enables longer drilling sections. With reduced ellipse of uncertainty, GyroLink service accommodates vertical, through-the-curve, horizontal, and extended-reach lateral drilling operations.
