A small number of LabQuest 2 units shipped in the Fall of 2016 that have an improper internal calibration. These LabQuests read certain sensors poorly. The most common symptom is that the LabQuest 2 will read a number around 80°C at room temperature...
Some of our sensors include a cable or cord, and it is tempting to wrap it around the sensor for storage. In a short time, the strain applied by this bending and twisting can damage the strain relief of the cord, and sometimes render the sensor unusa...
Ocean Optics USB2000 units may work properly with Logger Pro 3 (version 3.8.4 or newer).
If you have a Windows 8.1 computer or newer, a USB2000 will not work with Logger Pro 3. This is a Windows issue.
Also note older versions of Logger Pro 3 will n...
We do not recommend, nor do we support collecting other sensor data while using a spectrometer.
Please note that Logger Pro will allow you to collect data with a spectrometer and another probe, and will default to time-based data collection if yo...
There are a few possibilities here:
1) The column may be clogged, try running your Mini GC at high heat and pressure for an hour without injecting anything. Then inject a sample of acetone at the default temperature/pressure profile settings. If this...
You most likely need to change out the septum.
Signs that the septum on a Mini GC is going bad:
1) The injection feels too easy. With a good septum, when you insert the needle into the injection port it should feel like you're poking a pin through a...
Some networks are set up to allow devices to connect out to the internet, but prohibit communication between devices that are on the network. For example, the LabQuest would not be allowed to connect to an iPad, even though the LabQuest and the iP...
This information pertains to LabQuest 2 and LabQuest 3.
If you have an original LabQuest, see this article.
The soft access point function of the LabQuest 2 and LabQuest 3 is designed to work in situations such as outdoor data collection when you ...
Most people use a traditional compound microscope at 400x to see individual stomata on plant leaves. It is possible to see stomata as small white dots on the underside of a leaf at magnifications from 50-100x, but you will not be able to do real stom...
The best way to prevent damage to the Colorimeter is to prevent a spill from happening in the first place. Using lids on the cuvettes is the best way to accomplish this.
There are various models of Vernier Colorimeters (see What model Colorimeter...
