HM-ICP1 Sequential ICP-OES Spectrometer for Petrochemical Analysis

Product Introduction

The HM-ICP1 is a sequential scanning ICP-OES spectrometer engineered specifically for the petrochemical industry. It employs photomultiplier tube (PMT) detection with dual-beam R212/R928 detectors, enabling precise determination of trace element concentrations in oils, lubricants, and related petroleum products.

A distinguishing feature of this instrument is its direct oil sample introduction capability. Coupled with a semiconductor-cooled spray chamber operating at -20°C and oxygen-assisted injection, the system eliminates the carbon buildup issues commonly encountered with organic samples. This allows gasoline, diesel, and lubricating oils to be analyzed directly without complex acid digestion, significantly streamlining sample preparation workflows.

The optical system incorporates a 4320-groove imported grating paired with advanced optical path adjustment, delivering a resolution within 0.005nm — finer than the 0.008nm typical of conventional ICP spectrometers. The solid-state RF generator operates at 27.12 MHz with output power from 800 to 1600W, while a precision thermostat maintains optical path stability at ±0.1°C. With detection limits at ppb level for most elements and a linear range of 5–6 orders of magnitude, the instrument covers concentrations from trace to major levels without requiring standard curve changes.

Applications / Testing Items

• Gasoline and diesel: direct injection analysis of Si, P, Fe, Mn, Pb, and other trace elements

• Lubricating oils and additives: determination of 20+ wear metal elements after simple dilution

• Used lubricants: wear element analysis using optional high-salt nebulizer

• Crude oil and byproducts: multi-element analysis of 30+ elements

• Methanol, ethanol, and other petrochemical feedstocks: elemental content determination

• Automotive urea (DEF): Na, K, Ca, Mg, Al, Fe, Ni, Cu, Zn, Cr analysis

• Oilfield tracer rare earth elements

Features

1. Direct oil sample injection — semiconductor-cooled spray chamber at -20°C with oxygen-assisted delivery eliminates organic sample carbon buildup

2. Ultra-high resolution optical system — 4320-groove imported grating achieving resolution within 0.005nm, superior to standard 0.008nm instruments

3. High-sensitivity PMT detection — R212/R928 photomultiplier tubes with negative high voltage adjustable from -50 to -1000V; no cooling or purge gas required

4. Low operating cost — requires only 99.99% argon gas instead of 99.999% high-purity grade, reducing gas expenses by at least one-third

5. Precision constant temperature system — optical path maintained at ±0.1°C stability for reproducible wavelength accuracy

6. High-precision MFC gas control — all plasma, auxiliary, carrier, and oxygen gas flows managed by mass flow controllers with continuous adjustability

7. Full-auto ignition and matching — one-click startup with automatic impedance matching for reliable plasma ignition

8. Intelligent flame monitoring — fiber optic sensor detects abnormal flameout and automatically shuts down the instrument

9. 4-channel 12-roller peristaltic pump — consistent sample delivery with continuously adjustable rotation speed

10. 2D observation position adjustment — software-controlled torch positioning with signal feedback for optimal viewing height

11. Wide linear dynamic range — 5–6 orders of magnitude allows simultaneous high and low concentration measurement

12. Multi-element capability — analyzes 70+ elements with 5–10 elements per minute scanning speed
