1. Elab6600SN can determine solid samples immediately after determining volatile liquid samples without

   changing quartz tube and injector. Using only one sampling device, it can measure the total nitrogen

   content in gas, liquid (including volatile liquid) and solid samples without adding or replacing any

   device.

2. Elab6600SN has excellent repeatability and reproducibility of measurement results for measuring

    samples of µg/L concentration.

4. Elab6600SN adopts modular design, so that the instrument can be disassembled as single

    elemental analyzer, such as: Total sulfur Elemental Analyzer (Elab6600S), Total Nitrogen

    Elemental Analyzer (Elab6600N).

5. Repeatability:

    5.1 The total sulfur analyzer determines the standard substance for light oil sulfur content 

    (Standard Substance Number: GBW(E) 060108；standard value: 0.2mg/L), with an injection 

    volume of 2μL (The actual injection volume is 2μL). The RSD of no less than 5 consecutive

    measurements (data cannot be deleted in the process of measuring) is ≤ 10%.

    5.2 The total nitrogen analyzer measures the standard substance for light oil nitrogen content

     (Standard Substance Number: GBW(E) 060111；standard value: 0.2mg/L), with an injection 

    volume of 2μL The actual injection volume is 2μL). The RSD of no less than 5 consecutive 

    measurements (data cannot be deleted in the process of measuring) is ≤ 10%.

6. Linear:

    6.1 The total sulfur analyzer measures the "standard substance for light oil sulfur content" 

    (Standard Substance Number: GBW(E) 060108；standard values: 0.2mg/L, 0.5mg/L, 

    1.0mg/L), with an injection volume of 2μL (The actual injection volume is 2μL). Each

    standard sample is measured continuously for 5 times (data cannot be deleted in the 

    process of measuring). The average of the 5 integrated values of the three standard

     samples (0.2mg/L, 0.5mg/L, 1.0mg/L) is fitted once, and the linear correlation coefficient

    is ≥ 0.999. The integrated value of the 0.5mg/L sulfur standard sample is at least twice that

    of the 0.2mg/L sulfur standard sample.

    6.2 The total nitrogen analyzer measures the "standard substance for light oil nitrogen content"

    ((Standard Substance Number: GBW(E) 060111；standard values: 0.2mg/L, 0.5mg/L, 1.0mg/L), 

    with an injection volume of 2μL (The actual injection volume is 2μL). Each standard sample is

    measured continuously for 5 times (data cannot be deleted in the process of measuring). The

    average of the 5 integrated values of the three standard samples (0.2mg/L,0.5mg/L, 1.0mg/L) is

    fitted once, and the linear correlation coefficient is ≥ 0.999. The integrated value of the 0.5mg/L

    nitrogen standard sample is at least twice that of the 0.2mg/L nitrogen standard sample.

   Purpose: Used for measuring the total sulfur content and the total nitrogen content in gas samples, such as propylene gas, liquefied gas, etc; as well as liquid samples such as naphtha, gasoline, kerosene, diesel, benzene, toluene, etc.

   Compliance with standards and applicable methods: The total sulfur analyzer strictly follows the standards of ASTM D5453-19a, ASTM D6667-21, SH/T 0689-2000, and GB/T 11141-2014. The total nitrogen analyzer strictly follows the ASTM D4629-17 and SH/T 0657-2007 standards.
