Therefore, usually a step to increase the concentration of the sample is needed.

Higher air temperature also increase the concentration of ozone at ground level.

In order to increase the concentration, you have to add more (stuff) without increasing the volume.

First, it would sharply increase concentration in this critical market function.

The move increases the concentration of ownership in the cable industry.

High temperature and humidity levels can also increase concentrations of some pollutants.

This increases the concentration of all the other things in solution, thus increasing the boiling point.

Suppose we were to increase the concentration of CO in the system.

This is similar to the effect of increasing the concentration of a solution.

When all small particles do this, it increases the concentration of free molecules in solution.
