Product Description:

Bonaijer has launched a new type of large volume water treatment column, which is an extension of traditional solid-phase extraction disks. The special column tube shape design, combined with automated instruments, can achieve high-speed and effective enrichment of bulk water samples; Excessive drying of materials such as C18 during activation can affect the recovery rate and stability of the target substance; When the polarity of the analyte is too high, there may also be penetration of the target substance. In response to these shortcomings, the new AQ C18 series has added a certain proportion of polar functional groups on the surface of non-polar materials, solving the problems of traditional C18.

The unique design of LDC allows the sample bottle to be directly inverted onto the top of the column, making sampling convenient; The sample sampling speed is fast, not easily clogged, and suitable for the collection and processing of large volume samples in the environment; Low background, high sensitivity, strong universality, suitable for enrichment analysis of various polar and non-polar samples; Materials such as AQ C18 can be used for EPA method 525. ACA materials can be used to analyze highly polar compounds such as Methamidophos in water, which are difficult to adsorb by reverse phase materials and easily penetrate when loaded in large quantities, Cleanert^®ACA uses specially treated carbon materials, which have good adsorption and enrichment effects on trace amounts of Methamidophos in water, and can be eluted with a small amount of solvent.

SPE-D6 can be adapted to ordinary SPE columns with a glass funnel and PTFE adapter, and can be manually loaded into large volumes with Cleanert DEHP for analysis of phthalates in water.
