RESIDUE ON IGNITION

Portions of this general chapter have been harmonized with the corresponding t

exts of

the European Pharmacopoeia and the Japanese Pharmacopoeia. The portions that are

not

harmonized

are

marked

with

symbols

(

).

The

harmonized

texts

of

these

pharmacopeias

are

therefore

interchangeable,

and

the

methods

of

the

European

Pharmacopoeia and/or the Japanese Pharmacopoeia may be used for demonstration of

compliance instead of the present United States Pharmacopeia general chapter. These

pharmacopeias

have

undertaken not

to

make any unilateral

change

to this

harmonized

chapter.

这个章节的部分与欧洲药典和日本药典的相 应内容统一。而与其没有统一的部分则用

< br>标识出来。因此，药典中统一部分的内容是通用的，欧洲药典和（或）日本药典中关于灼炽

残渣的检测方法可以代替现行的美国药典对应章节中的方法。

这几部药典对这个 统一章节不

会做出任何单方面的改动。

The Residue on Ignition/Sulfated Ash test uses a procedure to measure the amount of

residual

substance

not

volatilized

from

a

sample

when

the

sample

is

ignited

in

the

presence of sulfuric acid according to the procedure described below. This test is usually

used for determining the content of inorganic impurities in an organic substance.

所谓炽灼残渣

（或硫酸盐灰分）

的检测，

就是测出样品经硫酸碳化再炽灼，

没 有从其中挥

发出的剩余部分的总量。这种方法通常用来检测有机物质中无机杂质的含量< /p>

Procedure

—

Ignite a suitable crucible (for example, silica, platinum, quartz, or porcelain)

at 600 ±

50

for 30 minutes, cool the crucible in a desiccator (silica gel or other suitable

desiccant), and weigh it accurately. Weigh accurately

1 to 2 g of the substance, or

the

amount specified in the individual monograph, in the crucible.

步骤：在

600

℃下炽灼一个合适材质的坩埚（例如，二氧化硅，铂金，石英，或者瓷

质）

30

分钟，在干燥器（硅胶或其他合适干燥剂）中冷却，精确称量它 的质量。精确称取
