Introduction
In high performance liquid chromatography (HPLC) analysis system, if the mobile phase of the carried sample containing bubbles,
abnormal peak will appear .Seriously affect the detection precision of the detector Although degassing of the mobile phase during pretreatment, but due to the n eed of mobile phase chemical properties and the analysis itself, when two mixed solution will produce bubbles. On line degasser can continuo usly remove gases from liquid phase , eliminate the unstable factors of the mobile phase and lower the baseline drift and noise, thus eliminated interference to detect oxygen by the electric chemical , fluorescence and uv detection . HDG series online degassing instrument adopts the advanced gasliquid membrane separation technology, chooses import original sensor, can automatically start the vacuum pump i n order to guarantee the degassing effect.Standard joint and make it a pipe connected to various types of HPLC system.
Working Principle
HDG series degassing instrument is using the principle of vacuum degassing.When the mobile phase in liquid pump driven by placed in a vacuum chamber to take off the trachea, tube inside and outside the general pressure makes the original mobile phase in the bubble molecules from continuous preci pitation separation membrane.Length in the vacuum chamber to take off the trachea design can satisfy the requirement of the conventional traffic degassing.
Main Features
- The advanced gasliquid membrane separation technology, the degassing efficiency is high, can meet the strict requirements of liquid chro matographic analysis system.
- The degassing system all closed, not change the chemical composition of the mobile phase.For flammable, volatile liquid degassing, can guarantee it will not overflow, so as to achieve the security of the degassing process.
- The installation is simple, easy to operate.The device of automatic startup system makes operator on line at a time, can be continuous use.
- Due to the international standard connectors and pipe, make it apply to all kinds and any manufacturer of high performance liquid system.
- Complete specifications, produced a series HDG degassing instrument 1-4 rhsnnale hioh met neffomuinr^ Wo slm rraviria rtiffp*ant r&aniramante of nistomafe imiwt nrininnl ni srtivitv
