3 Terms and definitions
The following terms and definitions apply to this document.
3.1 Detector tube
A device for determining the concentration of gas. It is composed of a glass tube filled
with a granular chemical substance that reacts with a specific gas and whose color
change is proportional to the concentration of the gas to be measured.
Note. The concentration of odor gas components can be read from the reading marked on the
surface of the glass tube.
4 Principle
measure the concentration of the odor components contained in the sampling bags
7.2.1.7 Use 100mL syringe (6.5) to extract, by three times, 250mL of ammonia that is
prepared as per 7.2.1.6, and inject into a new 50L sample bag (6.2) that is fully cleaned
by diluting gas (5.5) and is vacuumed.
7.2.1.8 Inject diluting gas (5.5) to 25L. This is 100μL/L ammonia sample gas.
Note. Small volume sampling bag can be used to replace 50L sampling bag.
7.2.2 Confirmation of ammonia sample gas concentration
7.2.2.1 Inject 3L of ammonia into 5L sampling bag by air pump (6.3). Use 100ml syringe
(6.5) to extract 100ml of ammonia sample gas from the sampling bag; measure its
7.2.2.2 Confirm the concentration of ammonia gas sample is within the range of
100μL/L ± 5μL/L.
Note. If the concentration of gas is not in this range, it cannot be used as ammonia sample gas.
Then the sample gas needs to be re-prepared.
7.3 Acetic acid
Use acetic acid (5.2) of purity 99.7% and diluting gas (5.5) to prepare acetic acid
sample gas of concentration 30μL/L ± 3μL/L.
7.4 Methyl mercaptan
Use methyl mercaptan standard gas (5.3) and diluting gas (5.5) to prepare methyl
7.5 Hydrogen sulfide
Use 100μL/L hydrogen sulphide standard gas (5.4) and diluting gas (5.5) to prepare
hydrogen sulfide sample gas of concentration of 4μL/L ± 0.4μL/L.
8 Test environment
Conduct the test under the standard atmospheric conditions specified by GB/T 6529.
9 Preparation of samples
9.1 The size or mass of the sample is shown in Table 1. Three samples are required
for each test.
read the value at the color-changing location. This value is the odor component
10.2.7 Record the average concentration of three odor components as A.
10.3 Blank test
10.3.1 Without the sample, test according to the steps of 10.2.2~10.2.6.
