在线离线TOC分析仪 纯水总有机碳分析仪  测定原理：仪器采用紫外氧化的原理，将水溶液中的总有机碳氧化为二氧化碳，并且测定其含量，二氧化碳的测试采用的是直接电导率法，通过测试经过氧化反应的水溶液总碳含量和未经过氧化反应的样品总无机碳的含量差值来测定总有机碳含量，即：总有机碳（TOC）=总碳（TC）-总无机碳（TIC）。

Determination principle: the instrument adopts the principle of ultraviolet oxidation to oxidize the total organic carbon in the aqueous solution into carbon dioxide and determine its content. The carbon dioxide test adopts the direct conductivity method. The total organic carbon content is determined by testing the difference between the total carbon content of the aqueous solution 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).

The instrument R & D Department of BG has the most outstanding and authoritative R & D force and technical team in the industry. It has long hired experts from the precision instrument department of Tsinghua University as technical consultants and established a new material testing instrument R & D center, which is an important technical guarantee to promote the improvement of the company's material testing technology and the innovation of test methods.

离线检测

离线检测时，仪器可从样品瓶或其它没有压力的容器直接取样。仪器管路冲洗和仪器校准应在离线状态操作。若样品中有不可溶性微粒，应经过滤膜（孔径60μm或更小）过滤后进入仪器，以防止样品中的微粒阻塞仪器。仪器的进样管为1/16英寸的Teflon管，经蠕动泵抽进管路中的水样流速约为0.5 ml/min。

Offline detection

During off-line detection, the instrument can directly sample from the sample bottle or other containers without pressure. Instrument pipeline flushing and instrument calibration shall be operated offline. If there are insoluble particles in the sample, it shall pass through the filter membrane (aperture 60 μ M or less) enter the instrument after filtration to prevent particles in the sample from blocking the instrument. The sampling tube of the instrument is a 1/16 inch Teflon tube, and the flow rate of the water sample pumped into the pipeline by the peristaltic pump is about 0.5 ml / min.

Carbon dioxide measurement cycle

The instrument detects one data every 4 minutes (including TOC value and conductivity value). TC and tic are detected independently in the 4-minute measurement cycle.

二氧化碳测量循环

仪器每4分钟检测得出一个数据（包括TOC值和电导率值），在4分钟的测量循环中TC和TIC是独立检测的。

使用与操作方法

开始检测并计入检测次数，检测完毕后显示最后一次检测结果，其中几次检测的结果均自动保存在查询记录当中。检测次数的设置方式为：用“选择”键移动光标，用“设置”键修改数字，按“确定”键进行确认，进入分析界面。先进行四次冲洗过程

Usage and operation method

Start detection and count the detection times. After detection, the last detection result will be displayed. The results of several tests will be automatically saved in the query record. The setting method of detection times is as follows: use the "select" key to move the cursor, use the "set" key to modify the number, press the "OK" key to confirm, and enter the analysis interface. Conduct four flushing processes first
