Crude Oil Testing Equipment - ICP for Crude Oils and Residual Fuels

ICP for Crude Oils and Residual Fuels

ICP for Crude Oils and Residual Fuels TT-5708

ICP for Crude Oils and Residual Fuels TT-5708 adheres to the ASTM D5708 Standard Test Methods for Determination of Nickel, Vanadium, and Iron in Crude Oils and Residual Fuels by Inductively Coupled Plasma (ICP) Atomic Emission Spectrometry. 

It facilitates the determination of nickel, vanadium, and iron in crude oils and residual fuels through inductively coupled plasma (ICP) atomic emission spectrometry. The test methods involve sample dissolution in an organic solvent or decomposition with acid. Comparative analysis of measurement results from both methods is conducted, along with investigation into spectral interference between each element, accuracy, and precision. The results meet satisfactory standards.

1. More than 70 different elements can be tested.

2. Enables simultaneous testing of multiple elements, allowing all elements to be tested at once with a single sample injection.

3. Offers rapid analysis speed, averaging about 5 elements per minute, with the fastest test speed reaching up to 10 elements per minute.

4. Features low detection limits, with most elements detectable at parts per billion (ppb) levels.

5. Provides a wide linear range, spanning up to 5-6 orders of magnitude, allowing for testing of both high and low content simultaneously without the need to change the standard curve.

6. Exhibits minimal chemical interference, resulting in more accurate test results.

Performance characteristics

Safe and Reliable Solid-State RF Power Supply

The instrument utilizes a solid-state RF power supply known for its safety and reliability. The radio frequency power supply features a compact size, high output efficiency, stable output power, and various safety protection functions including water circuit, air circuit, and overload protection. These features significantly enhance the instrument's safety and reduce the failure rate.

High Degree of Automation

The instrument achieves an exceptional level of automation, with all operations, aside from the power switch, executed through software. Intelligent software provides real-time feedback and prompts for various operations, ensuring efficient and error-free usage.

Automatic Ignition

The software enables fully automatic one-key ignition, with all parameter setting changes automatically managed. Advanced automatic matching technology ensures a high ignition success rate and simplifies the operation process.

High-Precision Airflow Control System

The instrument's plasma gas, auxiliary gas, and carrier gas operations are controlled by a high-precision mass flow controller (MFC). The flow rate is continuously adjustable, and the output airflow is highly accurate, guaranteeing the precision of test data.
