      • Overview
        • Alcohol NeedlEx is capable of concentrating methanol (the most difficult to concentrate organic solvent) by a factor of 50, and is also capable of concentrating low boiling point compounds such as acetone and acetaldehyde, as well as the gases propane and butane by factors of more than a 100. Gas samples containing methanol can be sampled up to 50 ml. Samples that do not contain methanol can be sampled up to 200 ml.

          Features of NeedlEx
          ① 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.
          ② 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 Teflon plugs included with each needle.
          ③ 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.
          ④ 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.

          The NeedlEx is used to concentrate and accurately analyze solvents present at extremely low concentrations of less than 10 ng/ml (a few ppm). As such, set sampling volumes as low as possible when there is a possibility that the compound to be sampled is present at a high concentration.
