Foreword
This Standard was proposed by the State Tobacco Monopoly Bureau.
This Standard shall be administered by the National Standardization Technical Committee
- Tobacco Smoke Materials Technical Sub-committee (SAC/TC 141/SC 8).
This Standard was drafted by organizations. National Tobacco Quality Supervision and
Inspection Center, Hongta Tobacco (Group) Co., Ltd., and Hongyun Honghe Tobacco
(Group) Co., Ltd.

Determination of arsenic, lead, cadmium, chromium, nickel,
mercury in tipping paper and tipping base paper for cigarette -
Inductively coupled plasma mass spectrometry
1 Scope
This Standard specifies the determination method of arsenic, lead, cadmium, chromium,
nickel, mercury in tipping paper and tipping base paper for cigarette – Inductively coupled
plasma mass spectrometry.
This Standard applies to determination of arsenic, lead, cadmium, chromium, nickel,
mercury in tipping paper and tipping base paper for cigarette.

3 Principle
After the sample is treated, USE 1% nitric acid to fix the volume. Under the selected
instrument parameters, the sample is ionized and forms aerosol. It is ionized under high
temperature argon gas plasma environment. After ionization, the ions extracted through
sampling cone, skimmer and lens ENTER into the mass analyzer for quantitative analysis.
Acquisition Mode Full quantitative analysis
Repetitions 3
7.2 PIPETTE appropriate amount of standard blank solution respectively. Different
concentrations’ arsenic, lead, cadmium, chromium, nickel mixed standard working
solutions, different concentrations’ mercury standard working solutions (4.9.5) and the
internal standard solution (4.8.2) ARE INJECTED into the inductively coupled plasma
mass spectrometry respectively. Under the selected instrument parameters, the ratio of
test elements arsenic, lead, cadmium, chromium, nickel, mercury contents AND the
internal standard element indium content ACTS as the ordinate; the ratio of test elements
arsenic, lead, cadmium, chromium, nickel, mercury mass numbers AND the internal
standard element indium mass number ACTS as the abscissa. ESTABLISH calibration
curves of arsenic, lead, cadmium, chromium, nickel, and mercury. PREFORM linear
regression to the calibration data. OBTAIN the regression equations of concentration
relation of arsenic, lead, cadmium, chromium, nickel, and mercury. R2 shall not be less
than 0.999.
7.3 PIPETTE sample blank solutions respectively. The sample solutions and the internal
standard solution (4.8.2) ARE INJECTED into the inductively coupled plasma mass
spectrometry. Under the selected instrument’s parameters, OBTAIN the ratio of test
elements arsenic, lead, cadmium, chromium, nickel, mercury ion mass number AND the
internal standard element indium mass number, SUBSTITUTE the ratio into the
regression equation obtained in 7.2. OBTAIN arsenic, lead, cadmium, chromium, nickel,
mercury contents in sample blank solutions and sample solutions.
