測試方法及其原理

國家藥典委員會發(fā)布的《中華人民共和國藥典2010版》二部中推薦采用在線和

離線兩種測試方法，還提供了系統(tǒng)適應(yīng)性試驗的操作方法。同時對測試總有機碳的儀

器也提出了要求，即首先要能區(qū)分無機碳和有機碳；并能排除無機碳對總有機碳的影

響；其次應(yīng)滿足系統(tǒng)適應(yīng)性試驗的要求；最后儀器應(yīng)具有足夠的檢測靈敏度。

要檢測樣品中的有機物濃度，必須將有機物分子分解并且轉(zhuǎn)化成能夠測量的單

分子形式，這樣就必須把有機物氧化成二氧化碳，并對生成的二氧化碳進行測量。目

前氧化的方法有四種：一、燃燒法；二、光氧化法；三、濕法氧化；四、光化學(xué)法。

氧化后有機碳測試的方法有差減法和直接法兩種。

工作原理

本儀器采用紫外氧化的原理，將樣品中的有機物氧化為二氧化碳，二氧化碳的測試采用的是直接電導(dǎo)率法，通過測試經(jīng)過氧化反應(yīng)的樣品的總碳含量和未經(jīng)過氧化反應(yīng)的樣品總無機碳的含量差值來測定總有機碳含量，即：總有機碳（TOC）=總碳（TC）-總無機碳（TIC）。

總有機碳分析儀可提供兩種更快更簡便的TOC檢測方法，即在線檢測和

離線檢測。

The expression of difference subtraction is TOC = tc-ic, that is, total organic carbon is the difference between total carbon (TC) and inorganic carbon (IC).

The oxidation method adopted by ta-1.0 analyzer is photooxidation method:

H2O HN (185nm) - > Oh? H?oh? organics) - > CO2 H2O

Carbon dioxide is measured by subtraction: TOC = TC－IC

TOC

In order to remove the CO2 generated by oxidation, the pH value of the sample needs to be lowered again. The CO2 was purged out and measured by a specially developed NDIR CO2 detector. The results are displayed as total organic carbon (TOC).

Test method and principle

Online and

The two offline test methods also provide the operation method of system adaptability test. At the same time, the instrument for measuring total organic carbon

The device also puts forward requirements, that is, first of all, it should be able to distinguish inorganic carbon from organic carbon; And the influence of inorganic carbon on total organic carbon can be eliminated

Ring; Secondly, it shall meet the requirements of system adaptability test; Finally, the instrument shall have sufficient detection sensitivity.

To detect the concentration of organics in a sample, the organic molecules must be decomposed and converted into measurable monomers

Molecular form, so that the organic matter must be oxidized to carbon dioxide, and the generated carbon dioxide must be measured. order

There are four methods of pre oxidation: first, combustion; 2、Photooxidation method; 3、Wet oxidation; 4、Photochemical method.

There are two methods for measuring the organic carbon after oxidation: subtraction method and direct method.

working principle

The instrument adopts the principle of ultraviolet oxidation to oxidize the organic matter in the sample into carbon dioxide. The direct conductivity method is adopted for the carbon dioxide test. The total organic carbon content is determined by testing the difference between the total carbon content of the sample after oxidation reaction and the total inorganic carbon content of the sample without oxidation reaction, that is, total organic carbon (TOC) = total carbon (TC) - Total inorganic carbon (TIC).

Total organic carbon analyzer can provide two faster and simpler TOC detection methods, namely online detection and
