With the digital display of the TruFlo Sample Monitor, you always know the actual rate of sample uptake to your nebulizer. This enhances the day-to-day reproducibility of your results and reduces the need to repeat measurements due to a blocked nebulizer, worn pump tubing or incorrect clamping of the pump tube. And the borosilicate glass sample path ensures that there is no memory effect or sample contamination. The TruFlo can even sound an alarm if the sample uptake is outside your specified limits.
The TruFlo is also ideal if you are relying on the natural aspiration of the nebulizer. Many operators, particularly of ICP-MS, use natural aspiration in order to eliminate the effect of peristaltic pump noise from their measurements. With the TruFlo, you always know what your sample uptake is and you can take immediate corrective action if there is any change. You can also record your sample flow so that you can check that you are using the same flow from day to day.
The actual sample flow is shown on the TruFlo's inbuilt digital display and a graph of the flow versus time can also be displayed on your computer.

The TruFlo is normally calibrated for aqueous solutions. With non-aqueous solutions, it can be reliably used to detect any change in the sample flow, but the actual flow reading will not be correct. If you routinely run non-aqueous solutions you can order a TruFlo calibrated for your specific application. When you order the TruFlo, simply add part # 70-TFCAL (TruFlo calibration service). You will need to specify what solution you are using and the TruFlo will be supplied pre-calibrated for your solution.
