GC Columns
Capillary Columns for GC and GC/MS Chromatography
Low Bleed, Temperature Stable, Inert, and Individually Tested Performance for All GC Applications
OPTIMA™ columns deliver unmatched performance, reproducibility, and durability for the most demanding GC or GC/MS applications.
From application-specific to a full spectrum of polar to non-polar phases, OPTIMA capillary columns are durable, high temperature resistive, and supplied with a COA for every individually tested column.
Build confident, transferrable methods. Our manufacturing process ensures column to column/lot to lot reproducibility for the most challenging separations.
Long column life and high-efficiency separations can now be confidently built-into the methods that you send throughout your organization.
Macherey-Nagel Capillary GC Columns Feature:
- Low bleed, temperature stable capillary coatings
- Inert, long-life stable performance
- Increased selectivity with highly reproducible results
- Individually tested columns are supplied with a COA
| Column | Stationary Phase | Description | Polarity |
|---|---|---|---|
| Optima-1 | 100% Dimethylpolysiloxane | Great all-purpose column. Excellent thermal stability. Separation by boiling point. | Non-Polar |
| Optima-5 | 5% Phenyl, 95% Methylpolysiloxane | Often the first choice in method development. Excellent thermal stability. Slight phase polarity gives greater selectivity. Supreme versatility. |  |
| Optima XLB | Silarylene phase, optimized silarylene content | Chemically bonded, cross-linked silarylene phase, optimized silarylene content for lowest column bleed | |
| Optima-Delta | phase with autoselectivity | Medium polar without CN groups. Analytes determine the polarity of the phase. Idea for MSD and PND detectors. | |
| Optima-1301 | 6% Cyanopropyl-phenyl, 94% methylpolysiloxane | Specifically designed for U.S. EPA Methods 608, 508, 8080 (pesticide analysis). | |
| Optima-624 | 6% Cyanopropyl-phenyl, 94% methylpolysiloxane | Specifically designed for U.S. EPA Methods 624 (environmental analysis). | |
| Optima-1701 | 14% Cyanopropyl-phenyl, 86% methylpolysiloxane | Unique polarity (relative to Optima-17). Ideal for alaysis of pesicides, drugs, and solvents. | |
| Optima-17 | 50% Phenyl, 50% Methylpolysiloxane | Greater phenyl content provides a unique polarity and higher thermal stability (relative to Optima-1701). Great peak shape for amines. Ideal for analysis of pesticides and drugs. | |
| Optima-210 | 50% Trifluoropropyl, 50% methylpolysiloxane | Excellent for EPA Methods 8140 and 609. Equivalent to USP Phase G6. | |
| Optima-225 | 50% Cyanopropyl-phenyl, 50% methylpolysiloxane | Ideal for separation of cis- and trans-fatty acid methyl esters (FAMEs). CLose equivalent to USP Phase G7. | |
| Optima-240 | 33% Cyanopropyl-phenyl, 67% Dimethylpolysiloxane | Recommended for FAMEs and dioxin analyses. | |
| Optima-Wax | Polyethylene glycol (PEG) | Ideal for analysis of polar compounds. Excellent for alcohols, aromatics, FAMEs, BETX, solvents, etc. | |
| Optima-FFAP | Nitroterephthalic acid modified Polyethylene glycol (PEG) | Ideal for analysis of volatile fatty acids, and phenols. Close equivalent to USP Phase G35 | Very Polar |
