Product Details
detailed introduction
Professional Hubei instrument maintenance and repair services——Years of technical accumulation, your trusted choice!
1、 Repair category:
-Gas chromatograph (GC): blocked injection port, aging chromatographic column, decreased detector sensitivity;
-Liquid chromatography (LC): unstable pump pressure, high detector noise, and flow path leakage;
-Mass spectrometer (MS): Vacuum system leakage, ion source contamination, mass axis deviation;
-Spectrometer (UV Vis/AAS): light source malfunction, wavelength calibration deviation, software crash;
2、 Maintenance category:
-Quarterly/annual maintenance: instrument cleaning, performance calibration, replacement of vulnerable parts;
-Preventive maintenance: cleaning of flow system, electrical safety testing, software upgrades;
-Customer repair report (describing the instrument brand, model, and fault symptoms);
-Engineers can contact and confirm within 2 hours for free remote diagnosis (complex faults require on-site visits);
-Provide a testing report and repair plan, and start the repair after customer confirmation;
-Repair completed, payment of fees, provision of repair records and warranty card;

German Total Organic Carbon (TOC) Analyzer LiquiTOCII Detailed Parameters and Specifications
1、 Basic Information
-Brand and Model: German Element (Analytik Jena) liquiTOCII
-Origin: Germany
-Listing date: September 14, 2010
-Application areas: pharmaceutical industry (purified water, injection water testing), electronics industry (ultra-high purity water), environmental monitoring, food industry, etc.
2、 Detection principle
1. Oxidation method:
-High temperature combustion catalytic oxidation: The sample is oxidized under the action of a platinum catalyst at 850 ℃, converting organic carbon into CO ₂.
-UV/Persulfate Oxidation: Combining UV light with persulfate oxidants, suitable for complex samples.
2. Detection method:
-Non Scattering Infrared Detector (NDIR): Quantitatively measure CO ₂ concentration and calculate TOC value.
-Support subtraction method (TC-IC) and direct determination method (NPOC).
3、 Core parameters
1. Measurement range - TC (total carbon): 0-30000 mg/L
-IC (total inorganic carbon): 0-35000 mg/L
-TOC (Total Organic Carbon): Calculated by TC-IC
2. Detection limit 4 μ g/L (TC and IC)
3. Accuracy repeatability error ≤ 3%, CV ≤ 1.5% (repeatability accuracy)
4. The analysis time is about 4 minutes for a single test, and about 3 minutes for TC and IC measurements each
5. Eight way valve design for injection method, supporting automatic injection, acid addition, and flow path cleaning
6. Injection volume 10-2000 μ L (variable)
7. Host function - built-in IC pre removal function (automatic acid addition and blowing)
-Automatic dilution (2-50 times)
-Blank zero water preparation function
8. The carrier gas requires high-purity air or high-purity oxygen (from gas cylinders)
4、 Hardware configuration
1. Display screen: 7-inch color touch screen
2. Power requirements: 220V, 50/60Hz, connected to a load of 1.9kVA
3. Work environment:
-Temperature:+15 ° C to+30 ° C
-SurroundingCO₂Concentration: Stable and below 800ppm
-Space requirement: The instrument should be at least 20cm away from the wall, with an overall size of approximately 120 × 55 × 35cm
4. Gas connection: Gas connection should be provided near the instrument, using a steel cylinder gas pressure reducing valve
5、 Software and Data Management
1. Operating software:
-Support inserting samples during continuous testing
-Output the results as a text file, compatible with Excel or other programs
-Database management: integrating data, metadata, and audit tracking to prevent tampering
-Permission management: Assign permissions by role (such as administrator, reviewer)
2. Compliance:
-Complies with the regulations of the Chinese Pharmacopoeia for TOC ≤ 500ppb in purified water and injection water
-Compliant with international standards (ISO, EN, USEPA, ASTM, APHA) and pharmacopoeial specifications (USP<643>, Ph. Eur.<2.2.44>)
6、 Special Features
1. Dual channel design: The Elementar LiquiTOCII online monitoring system supports real-time DIC monitoring.
2. Solid Sample Analysis: Optional HT 1300 Solid Analysis Upgrade Accessory, capable of analyzing carbon content in solid samples (with a maximum injection volume of 3g).
3. Nitrogen detection: optional nitrogen analyzer (chemiluminescence CLD or electrochemical ChD), in compliance with EN 12260 standard.
7、 Application Cases
-Urban dust analysis: used for detecting the total carbon content of ground dust in various functional areas of Jinhua City, with simple pre-treatment and high accuracy.
-Pharmaceutical industry: TOC monitoring of purified water and injection water to ensure compliance with pharmacopoeia standards.
-Electronics industry: TOC detection of ultra-high purity water in the semiconductor industry to ensure production quality.
8、 Certification and Standards
-Certification: Complies with NIEA methods, international methods (ISO, EN, USEPA, ASTM, APHA), and pharmacopoeial specifications of the Environmental Inspection Institute.
-Data reliability: Verified by third-party testing reports (such as Beijing Inspection Institute), supporting CMA/CNAS qualifications.
