詳細
Capillary GC column is also known as open tubular column. The carrier gas flows through the central aperture and is unrestricted throughout the length of the column. SP®-2340 is a cyanopropylsiloxane stationary phase, and has high polarity and temperature resistance.
用途:この非結合性カラムは、このクラスで最も高い極性を有しています。あらゆる汎用ビスシアノプロピルカラムの場合と同様に、脂肪酸メチルエステル(FAME)幾何異性体、ダイオキシン、炭水化物、および芳香族化合物の高温/低温分離に極めて効果的です。
USPコード:このカラムは、USP G5の要件を満たしています。
相:
USPコード:このカラムは、USP G5の要件を満たしています。
相:
- 結合なし
- ポリ(ビスシアノプロピルシロキサン)
