NeedlEx Sample Extraction Needle
Features of NeedlEx
- The NeedlEx enables easy extractions of samples and provides superior reproducibility. By attaching a NeedlEx needle to a gas sampler and simply aspirating a sample, the desired sample can be extracted selectively and accurately concentrated in a very short period of time.
- Adsorbed samples can be stored in NeedlEx needles. Extracted samples can be stored for approximately ten days by sealing both ends of NeedlEx needles using PTFE plugs included with each needle.
- No additional equipment is required for the adsorption and desorption of samples. Desorption of samples is performed using the heat produced by gas chromatograph injection ports. Extracted samples can be injected into GCs using gas tight syringes and 1 mL of N2.
- NeedlEx needles can be used repeatedly.By conditioning NeedlEx needles in GC injection ports for 3 minutes after each analysis, needles can be used approximately 25 to 30 times.
NeedlEx Types
- For organic solvents - Extractions of general organic solvents including ethyl acetate, isobutanol, methyl isobutyl ketone, toluene, xylene, and styrene, etc.
- For amines - Extractions of short chain amines including trimethylamine, etc.
- For fatty acids - Extractions of fatty acids (propionic acid, isobutyric acid, n-butyric acid, isovaleric acid).
- For alcohols - Sampling of air containing monohydric alcohols with up to 3 carbon atoms, and solvents such as acetone and diethyl ether with boiling points below 100?.
