測(cè)試方法及其原理

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

離線兩種測(cè)試方法，還提供了系統(tǒng)適應(yīng)性試驗(yàn)的操作方法。同時(shí)對(duì)測(cè)試總有機(jī)碳的儀

器也提出了要求，即首先要能區(qū)分無(wú)機(jī)碳和有機(jī)碳；并能排除無(wú)機(jī)碳對(duì)總有機(jī)碳的影

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

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

分子形式，這樣就必須把有機(jī)物氧化成二氧化碳，并對(duì)生成的二氧化碳進(jìn)行測(cè)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(jī)碳測(cè)試的方法有差減法和直接法兩種。

其中差減法的表達(dá)式為T(mén)OC=TC－IC，即總有機(jī)碳是總碳（TC）與無(wú)機(jī)碳(IC)的差值。

TA-1.0 分析儀采用的氧化方法是光氧化法：

H2O hn（185nm）‐>OH? H? OH? 有機(jī)物‐>CO2 H2O

二氧化碳的測(cè)量方式是差減法：TOC = TC－ IC

系統(tǒng)適應(yīng)性驗(yàn)證

系統(tǒng)適應(yīng)性驗(yàn)證是一種檢驗(yàn)TOC 分析儀氧化能力的試驗(yàn)方法，其計(jì)算公式如下：

儀器響應(yīng)效率（％）＝(（rss - rw）/（rs - rw）) * 100%

其中：

rss —— 為 1-4 對(duì)苯醌對(duì)照品溶液的響應(yīng)值；

rs —— 為蔗糖對(duì)照品溶液的響應(yīng)值；

rw —— 為總有機(jī)碳檢測(cè)用水的空白響應(yīng)值；

Testing methods and principles

The National Pharmacopoeia Committee recommends the use of online and offline methods in Part II of the 2010 edition of the Pharmacopoeia of the People's Republic of China

Two offline testing methods are available, and the operation method for system adaptability testing is also provided. Simultaneously testing the instrument for total organic carbon

The device also requires the ability to distinguish between inorganic carbon and organic carbon; And it can exclude the influence of inorganic carbon on total organic carbon

Sound; Secondly, it should meet the requirements of system adaptability testing; Finally, the instrument should have sufficient detection sensitivity.

To detect the concentration of organic compounds in a sample, it is necessary to decompose the organic molecules and convert them into measurable monomers

In molecular form, it is necessary to oxidize organic matter into carbon dioxide and measure the generated carbon dioxide. The eyes

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

There are two methods for testing organic carbon after oxidation: differential method and direct method.

The expression for subtraction is TOC=TC-IC, which means total organic carbon is the difference between total carbon (TC) and inorganic carbon (IC).

The oxidation method used by the TA-1.0 analyzer is photooxidation:

H2O hn (185nm) ->OH? H?OH? organic compounds ->CO2 H2O

The measurement method for carbon dioxide is subtraction: TOC = TC－IC

System adaptability verification

System adaptability verification is a test method for testing the oxidation ability of TOC analyzer, and its calculation formula is as follows:

Instrument response efficiency (%)=((RSS RW)/(RS RW)) * 100%

Among them:

RSS - the response value of 1-4 benzoquinone reference solution;

Rs - the response value of sucrose reference solution;

RW represents the blank response value of water used for total organic carbon detection;

Diverter

After entering the instrument, the water sample is divided into two equal flow paths. One path enters the carbon dioxide sensor through a delay coil to detect TIC, while the other path uses an oxidation reactor to decompose organic matter into carbon dioxide through the photocatalytic oxidation of a titanium dioxide film using a ultraviolet lamp (UV lamp), and enters the carbon dioxide sensor to detect TC. The total organic carbon can be calculated by this difference: TOC = TC–TIC。

Oxidation reactor

The instrument uses UV rays to oxidize organic compounds into carbon dioxide under the action of titanium dioxide photocatalyst. The oxidation reactor is a spiral quartz tube wrapped around a UV lamp. The UV lamp emits light at 185nm and 254nm to decompose aquatic products.

H2O hν(185nm)（TiO2）OH? H?

Hydroxyl radicals (OH?) can completely oxidize organic compounds to carbon dioxide.

Carbon dioxide measurement cycle

The instrument detects data (including TOC and conductivity values) every 4 minutes, and TC and TIC are independently detected during the 4-minute measurement cycle.
