48 Environmental Laboratory Direct adaptive HPLC column connectors


When changing from a Waters column to another brand like an Agilent Column, do you fi nd changing the ferrules and tubing (to maintain data integrity) time consuming? If so, Microsolv Technology Corporation have a solution that can help, introducing the MicroSolv™ Direct Adaptive (Di-Ad™) HPLC Column Connecters. They make this process much faster and easier without fussing with ferrules and tubing between column changes.


These Direct Adaptive Fittings were designed for you to avoid poor column connections and eliminate extra system volume. The universal pilot length of this spring-loaded connector adapts to any HPLC column for quick column swaps and prevention of poor connections that cause peak broadening. Available as a Single End Fitting or a Double End Fitting. You just simply screw the Di-Ad™ fi ttings into the column and the tubing pilot length will automatically be adjusted.

, ethane, etc) is possible due to the liquid nitrogen jet fl ow and cooling temperature of -196ºC. It enables automatic heart cut analysis of gases evolved from Multishot Pyrolyzer. The Selective Sampler SS-2010E is provides Heart-Cutting of desired Peaks and comes with a new Flow Switching System.


Various atmosphere gases (He, Air, etc) can be used. The Multi-Functional Sampler MFS-2015E makes splitless Pyrolysis possible without compromises, enabling 100x improved sensitivity (with LOQs in pg range). The MFS shortens analysis time by backfl ushing, solvent venting is also possible. It is the ideal tool for trace analysis, such as μ- and nano-Plastics, and additives detection. The new Cryogenic Mill IQ MILL-2070 is easy to use and simple to operate. Fast and effi cient high- speed milling is enabled by 3D/8-fi gure crushing ball motion. It pulverises samples at highest uniformity, homogeneity, and reproducibility.

software, which currently product line, is the basis for controlling the ACCQPrep HP150. By using this


software, the need for a standalone PC is eliminated. This results in a smaller, more compact unit with an integrated touch screen interface.


Enjoy the confi dence associated with Teledyne ISCO’s active solvent and waste level monitoring which reduces the risk of solvent spills. In addition, all sample and collection racks are RFID coded eliminating the potential of missed tubes. An exciting feature of the ACCQPrep HP150 is the Focus Gradient Generator. When activated, the user is prompted to run a preset scouting gradient then they select the target peak for purifi cation and the focused gradient is automatically programmed into the system.


Standard features include: fl ow rates from 1 to 150 mL/min allow development of Prep methods directly on the system without the need for pump head changes; operating pressure up to 6000 psi; choice of UV or UV-Vis plus ELSD and MS options.

Optimise Your Liquid Batching System: 5 Flow Meter Considerations email:


Probably the most recognised batch fi lling system is that of beverages, either directly into a glass or into bottles. But batching systems are also integral to the pharmaceutical and medical, and chemical and oil industries. Additive injection or chemical dosing are typical applications where fl ow meters are used to precisely control the amount of liquid dispensed, which is critical in such processes.

1. Repeatability is essential for a productive batching process


Titan Enterprises, a leading provider of fl ow metering solutions, have been designing and manufacturing accurate and reliable fl ow meters for batch control systems for over 40 years. Titan reports on the considerations required when choosing a fl ow measuring device for batching control.


Titan has published a white paper on the use of ultrasonic fl owmeters in high-speed batching but here we focus on the general batching system. We discuss fi ve key considerations when choosing a fl ow meter that will ensure your batching process runs smoothly.


Multiple uncertainties can change the amount of liquid being dispensed, causing a negative effect on the repeatability of the system. Controlling as many process variables as possible will help to ensure the accuracy and repeatability of fl ow measurement. Flowmeters, such as Titan’s mini turbines, can boast repeatability of 0.1% or better when operating under the same conditions.


2. The physical properties of the batch-fi lled liquid will dictate equipment requirements


The choice of fl owmeter may be limited by the properties of the liquid – whether it is viscous, volatile, corrosive, fl ammable, or contaminated with particles, for example. An oval gear fl owmeter would be ideal for batch-dosing high-viscosity liquids such as syrups, whereas a turbine fl ow device, such as Titan’s 800-series fl owmeters, are more appropriate for water and beer dispensing.


3. Maintaining constant process conditions


Changes in fl ow rate, temperature and pressure may cause the fl ow meter to function in an unpredictable dynamic way. Although maintaining operating parameters at a stable point is optimal, this may not always be possible and fl uctuating fl ow rates for example, can be compensated for by using a higher specifi cation measuring device, such as Titan’s Atrato® ultrasonic fl owmeter.


4. Constant liquid fl ow or pulsations?


Keeping the overall fl ow constant and avoiding any pulsations within the batching system will prevent aliasing and incorrect fl ow readings over the batch operating cycle. If pulsation is inherent, the choice of fl owmeter is crucial in mitigating the effects of pulsating fl ow.


5. Limiting system inertia


Simple adjustments to the batch system design, such as control valve specifi cation and the positioning of the fl ow meter, can help to offset the effects of inertia.


Choosing the correct fl ow meter for a batch system can be complex and Titan Enterprises are happy to help you fi nd the best fl ow meter solution for your process and plant.
