Agricultural Applications

128
They say the grass is greener on the other side. Give us a sample of that soil, and we’ll be able to figure that out for you. FIAlab Instruments specializes in instruments that analyze soil content and nutrition. Utilizing flow injection (FIA) technology invented by our founder, our instruments analyze soil and plant matter for nitrate, phosphate, ammonia, and much more. Here are just a few of the benefits for using our systemsin your soil lab:

SIA Pump Troubleshooting

129
Troubleshooting Pump Issues In sequential injection, pump troubles are the most common issue. These issues can range from poor precision or accuracy, pressure surges, aspiration air leaks and plunger repositioning errors. In order to identify which facet of the pump is causing the problem, one must look at more than just the pump itself. More often than not, exceeding the syringe pump’s physical/mechanical limitations is the main cause.

The Coefficient of Determination vs Relative Standard Error

104
The coefficient of determination, or R 2 value, is a measure of how well a set of data fits a calibration curve. This is the metric that is used almost universally by agricultural and environmental laboratories across the county. The closer this value approaches 1, the better a calibration curve fits the range of standards.

Multivariate Analysis: An Advancement for Flow Injection

74
FIAlab incorporates a multivariate analysis feature in FIAsoft and SIAsoft. This tool allows our analyzers to reach lower quantitation limits of detection than ever before. This advanced data processing tool reduces noise 3-5-fold uncovering peaks with concentrations in single digit parts per billion. This result yields a striking distinction between pre and post-processed data shown below:
