Orsat

The even values of the molecular weights of the gases appearing in an analysis by an Orsat are:

Steam, Its Generation and Use

Orsat apparatus, or some modification thereof, should be employed.

Steam, Its Generation and Use

In one instance that came to our attention, in using an Orsat apparatus where the cuprous chloride solution was believed to be fresh, no CO was indicated in the flue gases but on passing the same sample into a Hempel apparatus, a considerable percentage was found.

Steam, Its Generation and Use

For analyzing the gases of blast-furnaces the various apparatus of Orsat have long been employed; but, by reason of its simplicity, the burette devised by Dr. Bünte, and shown in the accompanying figures, is much easier to use.

Now withdraw a sample of the mixed gases into the Orsat and analyse.

The analysis made by the Orsat apparatus is volumetric; if the analysis by weight is required, it can be found from the volumetric analysis as follows:

Steam, Its Generation and Use

As the percentage of CO_ {2} in these gases increases, there is a tendency toward the presence of CO, which, of course, cannot be shown by a CO_ {2} recorder, and which is often difficult to detect with an Orsat apparatus.

Steam, Its Generation and Use

When the evolution of gas has ceased, remove the apparatus from the incubator; clear out the wax from the nozzle of the three-way tap (first adjusting the tap so that no escape of gas shall take place) and connect it with the Orsat.

By means of hollow needles forced through the leather-like material of the suit Seaton drew off a sample of the atmosphere within, into an Orsat apparatus, while Crane made pressure and temperature readings.

Among this may be mentioned indicators, thermometers, gauges, planimeters, with standards for their correction and calibration; two types of Orsat apparatus; separating and throttling calorimeters, etc. FIELD WORK IN CIVIL ENGINEERING.
