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。

其中差減法的表達式為TOC=TC－IC，即總有機碳是總碳（TC）與無機碳(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? 有機物‐>CO2 H2O

二氧化碳的測量方式是差減法：TOC = TC－ IC

系統(tǒng)適應(yīng)性驗證

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

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

其中：

rss —— 為 1-4 對苯醌對照品溶液的響應(yīng)值；

rs —— 為蔗糖對照品溶液的響應(yīng)值；

rw —— 為總有機碳檢測用水的空白響應(yīng)值；

 分流器

水樣進入儀器后分成相同流量的兩路，其中一路通過延遲線圈進入二氧化碳傳感器，檢測TIC，另一路通過氧化反應(yīng)器利用紫外燈（UV燈）加二氧化鈦薄膜光催化氧化作用將有機物分解為二氧化碳，進入二氧化碳傳感器檢測TC?？傆袡C碳可通過這個差值計算得到：TOC = TC–TIC。

氧化反應(yīng)器

儀器利用UV射線在二氧化鈦光催化劑的作用下將有機化合物氧化成二氧化碳，氧化反應(yīng)器是一個UV燈外包螺旋形的石英管。UV燈發(fā)出185nm和254nm的光線，使水產(chǎn)生光分解。

H2O hν(185nm)（TiO2）? OH?  H?

有機物  OH?? CO2 H2O

UV燈的使用壽命為6個月，當(dāng)更換時間到期時儀器將出現(xiàn)警告信息，提醒用戶更換UV燈。

二氧化碳測量循環(huán)

儀器每4分鐘檢測得出一個數(shù)據(jù)（包括TOC值和電導(dǎo)率值），在4分鐘的測量循環(huán)中TC和TIC是獨立檢測的。

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.
