Yes, you can make the data files smaller (for details, see the User Manuals):
How do I install and activate the QTools software?
There are two types of registration strings, temporary and permanent. A temporary string is 25 characters long and will expire in a few days. A permanent string is 30 characters long and can only be obtained after you have sent the file ‘QTools reg info.qri’ (from the folder specified in the information dialog box that QTools presents – depends on the OS) to [email protected]. This file will automatically be generated by the QTools registration manager. If you have an email program running, QTools can automatically use this to create an email. All you then have to do is to click on ‘Send’ in the mail QTools created for you.
The ‘QTools reg info.qri’ file contains information that identifies your computer and this information will be coded into the registration file you will receive from Q-Sense. QTools will periodically check if there is a match between the registration string and the ‘QTools reg info.qri’ file. If there is no match, QTools will notify the user and ask for a valid registration string. QTools cannot be run from a local server but needs to be installed locally on each computer.
Please also note that after changing hard drive or upgrading from Windows XP to 7, a new QTools registration string needs to be generated after software reinstallation.
Please note that it is preferable to identify this file with a name chosen so that it is possible to know which PC it came from. The reason is that each registration file is unique. It is especially important if there are several QTools computers in the facility.
Open QTools. Go to ‘Help’ › ‘Launch Registration Manager’, then click ‘Remove registration’. This will disable QTools on that computer. Note that the registration string is connected to the computer and not the user. Also, it is necessary to have administrative rights in order to run QTools registration manager. QTools, however, can be run under normal user rights.
The new user can then apply for a new registration string on another computer. For details see the FAQ ‘How do I install and activate the QTools software?’.
The maximum acquisition rate is more than 200 data points per second. If default settings are used, an average function is employed that gives around 100 data points per second, distributed according to how many modules and frequencies that you have chosen to acquire. The exact number of data points taken depends on how fast the signal is damped, which means that a measurement in water gives a higher kinetic resolution than one in air, and higher frequencies give a higher resolution than lower ones.
QSoft is trying to sample as many points as possible with the given settings (more resonances and more averaging will slow down sample speed). For each point, a lot of data is being transferred from electronics to the PC, where it is processed. So depending on how much the PC is loaded with other processes it will have a slightly different sampling speed.
Clicking ‘Automatically optimize all resonances’ will give the default settings for a measurement run. The optimization of driving and recording of the crystal is dependent on D and the overtone number, which means that different sensors (flow modules) can have different settings.
Make sure you have got the latest version of QSoft401 installed. This version of the software will take care of the problem automatically or guide you through the steps necessary to solve it.
There are no particular settings for each type of solvent, such as toluene or ethanol, but they should be similar to water settings. What is important is that the decay curve window looks normal, i.e. the time interval used for data sampling of the sinusoidal decay curve is properly chosen: it should be long enough to include a sufficient number of oscillation periods, allowing a good mathematical fit to it, but not too long so that the decay curve has leveled out within the window. Use the ‘Sample frequency’ to change the length of the decay curve capturing window.
The wavelength, set under ‘Settings’ › ‘Edit…’ › ‘Acquisition’, is the number of data points used in the fitting of a decay curve. Together with the sampling frequency they give the decay fitting time
QSoft and QTools are compatible with Windows 7, 8 and 10 platforms. We do not support Vista and XP but current versions of the software may work.
Please note that you need a native Windows installation (it will not work properly on virtual Windows for e.g. Mac).
There is currently no version of QTools for the Mac OS. It may be possible to install it on a dual boot Mac, with Windows XP or higher installed on it. QTools cannot be registered on Windows emulation software made for the Mac OS, however. You will need to partition your hard disk, then install a licensed copy of Windows on it.
