General Analysis
KF-800
K-800
KD-800
- Standard organic solvent SEC column
- Supports a wide range of applications from low to high molecular weight compounds
- Fulfills USP L21 requirements
- KF-800 - tetrahydrofuran (THF) shipping solvent
- K-800 - chloroform shipping solvent
- KD-800 - dimethylformamide (DMF) shipping solvent
Rapid Analysis KF-600
- Achieves approximately halved analysis time compared with standard columns
- The amount of solvent used is reduced to about a third
- Improved applicability of solvent replacement
- Fulfills USP L21 requirements
KF-400HQ
- About 1.5 times better separation performance than standard columns, obtains higher resolution
- About 4 times better sensitivity than that of standard columns, supports high sensitivity analysis
- The amount of solvent used is reduced to about a third
- Improved applicability of solvent replacement
- Fulfills USP L21 requirements
Ultra-Rapid Analysis HK-400
- Newly developed styrene divinylbenzene copolymer monodisperse particles
- Analysis time reduced to about one sixth of conventional column's analysis time
- Low column pressure even under high flow rate, does not require its use with UHPLC device
Linear Calibration Type LF
