![]() Furthermore, they strongly reduce the light scattering that arises when using round-section capillaries. They are transparent and they can be easily inserted into micro-fluidic circuits. Rectangular glass micro-capillaries are an interesting alternative to custom-designed microfluidic chips since they are low-cost devices, available in several formats, that do not require any complex and expensive micromachining facility. Another work exploits a circular capillary as a waveguide in combination with optical fibers and an LED for fluoride detection in water samples. In, a round-section capillary with a six-port valve was exploited to measure the percentage of ethanol in a liquor by measuring absorbance at 23 nm. For example, in a photometric flow cell realized with circular glass capillaries and a reflective coating layer was exploited for absorption analyses of polluted waters. Other solutions feature round-section glass capillaries. Many works presented in the literature are based on complex waveguide or optrode structures that need to be custom-fabricated and usually make use of laser diodes or LEDs for single- or double-wavelength measurements. Among all the optical techniques, absorption spectroscopy is a very well-known method used to identify the chemical composition of a sample. They are based on the analysis of the variations in the characteristics of light that interacts with an analyte under investigation. Problems can arise when your hardware device is too old or not supported any longer.Capillary-based optical sensors are very diffused and exploited for a great variety of applications. This will help if you installed an incorrect or mismatched driver. Try to set a system restore point before installing a device driver. It is highly recommended to always use the most recent driver version available. Also make sure you constantly check with our website to ensure that you don’t miss a single new release. ![]() Therefore, if you consider applying this release, hit the download button, take into account all the aforementioned aspects, and update the device’s firmware. Moreover, it’s best that this task be performed in a steady power environment such as the one ensured by a UPS unit. When it comes to the update steps, due to the large variety of devices and numerous ways for installing a new firmware, it is recommended that you carefully read and understand the upgrade steps, and consider applying a different firmware only when you have familiarized yourself with the update method.Īs the installation process is most of the times quite risky, this step should be taken by users that have the ability to successfully complete the update regular users may initiate it at their own risk. However, bear in mind that applying an older firmware isn’t recommended and might not always be possible. On the other hand, downgrading the firmware version can recover the device’s functionality in the event of a software update either turning up faulty or causing the unit’s overall performance to drop. ![]() Print out these instructions for use as a reference during the installation process.Īpplying a newer firmware version than the one already installed on your unit can bring various enhancements, include workarounds for diverse problems encountered by the device, and improve or add newly developed features. The Taskbar should be clear of applications before proceeding. To ensure that no other program interferes with the installation, save all work and close all other programs. During the installation of this file, be sure that you are logged in as the Administrator or as a user with Administrative rights. ![]() Engineered using the highest level of quality standards, this controller supports a wide variety of industry standard I/O’s. The ProCommander 2 is the most comprehensive controller available. ![]()
