GC Column 007-1, 15 m x 0.32 mm ID, 5 µm Film
The non-polar 007-1 dimethylpolysiloxane phase, which separates compounds according to boiling point, is probably the most frequently used phase type in GC. Bonding and crosslinking this general purpose GC phase increases the resistance to degradation by rinsing, large solvent injections and the deposition of non-volatiles. The 007-1 phase offers excellent efficiency and thermal stability. In addition, this non-polar phase is less susceptible to oxidation and hydrolysis than phases incorporating more polar functional groups.

General Area of Use
PHAT™ Phase Columns
In addition to the standard range of column configurations offered with the 007-1 phase type, our unique coating technology allows us to extend the functional range of columns coated with the 007-1 phase by the application of very thick films. For example, films up to 3.5 microns on 0.10mm I.D. fused silica and 18.0 microns on 0.53mm I.D. fused silica are now possible. These PHAT Phase™ thick film columns are ideal for low molecular weight analyses previously performed on packed columns.
Advantages of PHAT PHASE™ fused silica capillary columns include:
- greater sample size for trace analyses of very volatile compounds
- increased retention of volatile compounds leading to higher elution temperatures
GC analyses of gases and other types of low molecular weight compounds have been traditionally accomplished on packed columns with heavy loadings or adsorbent type columns. More recently, porous layer open tubular (PLOT) capillary columns have been utilized in the separation of low molecular weight applications despite the drawbacks in using these types of columns such as sample adsorption and bead migration within the column.
Attempts have been made to use 'thick filmed' wall coated open tubular (WCOT) capillary columns but the films have typically been confined to a maximum of 8.0 microns due to limitations in conventional column coating technology. While these 'traditional' thick film columns have been used for some for low molecular weight applications, they could not attain the separations and sample loadings that could be achieved on packed columns.
By employing our proprietary coating technique we are now able to reproducibly manufacture fused silica capillary columns having phase ratios comparable to heavily loaded packed columns. The PHAT Phase™ columns are available with 007-1, dimethylpolysiloxane and our 007-5, 5% phenyl methylpolysiloxane phases in lengths up to 30 meters. These PHAT Phase™ thick film capillary columns are ideal for low molecular weight analyses previously performed on packed columns.
