Laboratory Products 77 Ensuring the Accuracy of Reagent Dispensing Pumps
Testa Analytical has launched a new PC App to expand its versatility and further simplify using their Solvent Line Monitor device.
The intuitive PC App allows easy configuration of the device enabling users to set the required level of sensitivity for monitoring for the presence of undissolved gas bubbles that can affect the accuracy of any reagent dispensing pump.
Dissolved gases are well known to have an impact on the performance of reagent dispensing pumps. A common solution to address this problem is to install a vacuum degasser on the inlet side of the pump. However undissolved gas bubbles will pass through largely unaffected by the degasser which can lead to unreliability in dispensing volumes. Several companies are now using the Solvent Line Monitor to detect undissolved gas bubbles in real-time. In these installations,
the digital output from the device detecting an undissolved gas bubble is being used to stop the dispensing pump before it can negatively affect dispensing accuracy. As a result of implementing the Solvent Line Monitor, these organisations have improved the product quality and yield from their production processes.
It has also been shown that the Solvent Line Monitor is a valuable monitoring device for safeguarding the performance of your HPLC system from problems caused by undissolved gas bubbles or a pump solvent reservoir running dry.

Why Infrared Radiation Heating?
Infrared radiation heating refers to the spectrum between 0.7um- 100um of light waves, emission and transmission accompanied by obvious, directional energy transmission. The energy transmission does not need any media, even in vacuum space. The infrared heating uses an electromagnetic wave with a wavelength of 2.5 to 15 um. This speed is much higher than the rate of conduction and convection. Thanks to this
radiation heating technology, Wiggens hotplate and stirrer can be used for speedy heating up for various shaped vessels including round- bottom flasks, and the solution inside can be heated up to a maximum temperature of 450°C in a very short time.
The hotplate and stirrer, with its advanced infrared radiation technology, is characterised by direct, clean and safe heating compared to oil heating. The high infrared permeability ensures that the heating energy is transferred quickly and with very limited loss, i.e. it heats liquids fast and thus saves time and energy. PID control or advanced ICC technology enable good temperature stability. If the Pt-100 sensor is connected, temperature-controlled work with stability of ± 2°C can be reached in most applications.
