Description

The Elite-624 column is a specially engineered, low to mid-polarity (6%-cyanopropylphenyl)-dimethylpolysiloxane phase. The unique polarity of the Elite-624 column makes it ideal for analyzing volatile organic pollutants and it is recommended in U.S. EPA methods. Although the Elite-502.2 column is recommended in many methods, the Elite-624 column offers better resolution of early eluting compounds. The Elite-624 phase produces greater than 90% resolution of the first six gases in EPA Methods 8260 and 524.2. This stationary phase is especially well-suited for EPA Method 524.2 since it resolves 2-nitropropane from 1,1-dichloropropanone, which share quantification ion m/z 43 and must be separated chromatographically. Equivalent to USP G43 phase. Well suited for EPA methods 524.2 and 8260.

FAQs

Question: What are the dimensions of the Elite-624 capillary column?

Answer:60 m length, 0.25 mm internal diameter and 1.40 µm film thickness.

Question: What types of analyses use an Elite-624 stationary phase?

Answer:Gas chromatographic separation of volatile organic compounds and residual solvents in suitable methods.

Question: Is the 1.40 µm specification the column internal diameter?

Answer:No. It is the stationary-phase film thickness; the column internal diameter is 0.25 mm.

Application Note

The PerkinElmer Elite-624 capillary gas chromatography column is a 60 m fused-silica separation column with a 0.25 mm internal diameter and 1.40 µm stationary-phase film. The 624-type phase provides selectivity suitable for separating mixtures of volatile organic compounds and residual solvents under an appropriately developed temperature program. The long 60 m column length can support resolution of complex volatile mixtures, with analysis time, carrier-gas flow and temperature programming adjusted to the laboratory's chromatographic method. The 1.40 µm film thickness is an important part of its retention and capacity characteristics and should not be confused with the internal diameter or a different 624 column format. Correct installation requires checking column end fittings, inlet positioning, detector connection and available instrument pressure capability. Column conditioning and leak-free connections help maintain stable baseline performance. The product is one analytical GC column rather than a cartridge, guard column or complete gas chromatograph.
