KN-7111 ICP for Middle Distillate Fuels

KN-7111 inductively coupled plasma atomic emission spectrometry (ICP-AES) covers the determination of selected elements in middle distillate fuels. The concentration range of this test is approximately 0.1 to 2.0 mg/kg. The test may be used for concentrations outside of this range; however, the precision statements may not be applicable. Middle distillate fuels covered in this test method have all distillation fractions contained within the boiling range of 150 to 390°C. This includes, but is not limited to, diesel fuels and aviation turbine fuels.

Instrument advantage

1. There are more than 70 kinds of elements can be tested.

2. Simultaneous testing of multiple elements, all elements are tested at the same time with one sample injection.

3. Fast analysis speed, about 5 elements per minute, and the fastest test speed can reach 10 elements per minute.

4. The detection limit is low, and most elements can reach ppb level.

5. The linear range is wide, up to 5-6 orders of magnitude, and high and low content can be tested at the same time without changing the standard curve.

6. Less chemical interference and more accurate test results.

Performance characteristics

Safe and reliable solid-state RF power supply

The radio frequency power supply used in the instrument has small size, high output efficiency, stable output power, and various safety protection functions such as water circuit, air circuit and overload, which greatly improves the safety of the instrument and reduces the failure rate of the instrument.

High degree automation

The instrument has a very high degree of automation, besides the power switch, all operations are completed by software. Intelligent software can provide real-time feedback and information prompts for various operations in real time.

Automatic ignition

The software can achieve fully automatic one-key ignition, and all parameter setting changes are automatically completed. With advanced automatic matching technology, the ignition success rate is high and the operation is simple.

High-precision airflow control system

The plasma gas, auxiliary gas, and carrier gas in the instrument work are all controlled by a high-precision mass flow controller (MFC). The flow rate is continuously adjustable and the output air flow is highly accurate, ensuring the accuracy of the test data.
