IDEX MX series II MXP7900-000 2-position, 6-port motorized valve
The MXP7900-000 is a DuraLife 2-position, 6-port motorized valve. The small compact stand-alone unit is typically used as a switching and/or injection valve.

Atlantic and Pacific SPE disks selection guide for Horizon 5000 and 3100 systems
This is a selection guide for Biotage Atlantic and Pacific disks to be used with Horizon 5000 and 3100 systems, respectively.

The role of the carbon cartridge in the one-pass system (Horizon 5000)
The one-pass system using the one-pass disk and carbon cartridge is an effective way to extract a large suite of analytes with different characteristics with good recovery. The carbon cartridge can be used to capture additional analytes that are more polar and have large water solubility.

Analysis of extract drying criteria for oil and grease method 1664A/B using Horizon 3100
The evaluation was performed using the Horizon 3100 oil and grease extraction system. The system was set up with the larger disk holder (90 mm). The evaporation step, prior to gravimetric measurement was performed using the Speed-Vap IV automated evaporation system with the 5-position rack and 105 mm aluminum weighing pans.

U.S. EPA method 625.1 – method and instrumentation for semi-volatiles with SPE
This poster demonstrates successful sample preparation using an automated, one-pass SPE system. In this configuration, all analytes of interest are extracted with a single pH adjustment. The success of the extraction is due to the use of a mixed mode SPE disk which contains several functionalities.

Quantitative determination of diquat and paraquat in drinking water via EPA method 549.2 using Horizon 5000
The scope of this application note is to demonstrate the process used to extract diquat and paraquat from reagent water using the Horizon 5000 in tandem with the ISOLUTE C8(EC) 500 mg/6 mL solid phase extraction cartridge.

Improving SPE disk extraction technology for US EPA wastewater method 625.1
This note examines the resuslts from an initiial demonstration of capability (DOC) with one liter samples utilizing automated disk solid phase extraction (SPE) for US method US EPA method 625.1.

Automated SPE and GC-MS analysis of tap water samples according to EN 16693:2015 for organochlorine pesticides
This note demonstrates the performance of automated disk-based solid phase extraction (SPE) for concentration of organochlorine pesticides from whole water, prior to GC-MS analysis, following the requirements of EN16693:2015.

Automated SPE of PAH compounds using the Horizon 5000
This work describes the evaluation of three different disk media type to better understand the performance of each for a wide range of PAH compounds. The media evaluated includes C18 high-capacity, DVB and HLB-M.

PAH analysis in drinking water using automated disk SPE
This note demonstrates that automated SPE for preparation of PAHs in drinking water gives excellent results, meeting the requirements set forth in US EPA method 550.1. In addition, the time for preparation is efficient and samples are prepared and ready for HPLC analysis in less than 2 hours.
