1. Elab6600N 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. Elab6600N has excellent repeatability and reproducibility of measurement results for measuring

   samples of µg/L concentration.

4. Elab6600N adopts modular design, so that the instrument can be used as a two-element

   combination analyzer, such as: total sulfur and total nitrogen analyzer (Elab6600SN), etc.

5. Repeatability: 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: 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 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 nitrogen analyzer strictly follows the ASTM D4629-17 and SH/T 0657-2007 standards.
