Ghost Trap DS/DS-HP (for UHPLC)
Mobile phase cleaner for HPLC
The Ghost Trap DS was co-developed with Daiichi Sankyo Co., Ltd. It has been designed to effectively adsorb impurities in the mobile phase in order to reduce the time required for method development and impurity analysis.
The 100 MPa pressure resistance of the Ghost Trap DS-HP allows it to be used with UHPLC systems. This permits the effective use of the Ghost Trap DS for method development by UHPLC and subsequent transfer to conventional analysis.
* DS: Abbreviation of Daiichi Sankyo (D) and Shimadzu (S)
Consistently traps impurities, even in organic solvents

|*1||Note that a delay volume equivalent to the internal volume of the product occurs if the product is installed downstream of the gradient mixer or the confluence of two pumps.|
|*||The product service life differs according to analysis conditions, such as the mobile phase used.|
|*||In analysis using an ion-pairing reagent, the ion-pairing reagent may be retained in the product, influencing the retention time and peak shape.|
|*||Before connecting the analytical column, be sure to thoroughly clean the flow path with mobile phase (close to the final concentration for gradient analysis).|
|*||Note that some impurities may not be removed.|
|*||When performing high-pressure analysis exceeding 35 MPa with a UHPLC system, connect the gradient mixer to the Ghost Trap DS-HP with pipe for UHPLC (e.g.228-53137-97).|
