Full title and description

ISO 10362-1:2019 — Cigarettes — Determination of water in total particulate matter from the mainstream smoke — Part 1: Gas‑chromatographic method. This International Standard specifies a gas‑chromatographic procedure for determining the water content of total particulate matter collected from mainstream cigarette smoke.

Abstract

The document defines a gas‑chromatographic analytical method for measuring water in total particulate matter (TPM) produced by mainstream cigarette smoke. Smoking and TPM collection are normally performed in accordance with ISO 4387, but the method is also applicable to TPM obtained from non‑standard smoking regimes. Where gas‑chromatography cannot be used, the Karl Fischer method (ISO 10362‑2) is the alternative.

Scope

ISO 10362‑1:2019 specifies a gas‑chromatographic method to determine the water content in total particulate matter collected from the mainstream smoke of cigarettes. The procedure covers sampling (normally using the smoking and TPM collection procedures of ISO 4387), sample preparation, chromatographic measurement, calibration and result expression. It is intended for use in routine laboratory, quality control and research settings; where gas‑chromatography is impracticable, ISO 10362‑2 (Karl‑Fischer method) provides an alternative.

Key topics and requirements

• Definition of TPM (total particulate matter) sampling context — normally used with ISO 4387 smoking/collection procedures.
• Gas‑chromatographic analytical procedure for quantitative determination of water in TPM (instrumental conditions, carriers, columns and detectors as required).
• Calibration and use of appropriate reference standards and controls to ensure accuracy and repeatability.
• Sample handling, transfer and preparation to avoid water loss or contamination during analysis.
• Expression and reporting of results, including notes where an alternate method (Karl‑Fischer) is used.

Typical use and users

Used by tobacco product manufacturers, independent analytical and regulatory laboratories, research institutions and quality‑assurance teams that perform compositional analysis of cigarette mainstream smoke. Typical applications include product testing, method validation, comparative studies and regulatory compliance work.

Related standards

Key related standards include ISO 4387 (determination and collection of mainstream smoke total particulate matter) and ISO 10362‑2 (Karl‑Fischer method for water determination in smoke condensates). Earlier editions of ISO 10362‑1 (1991, 1999 and amendments) were superseded by the 2019 edition.

FAQ

Q: What is this standard?

A: ISO 10362‑1:2019 is the third‑edition ISO standard that specifies a gas‑chromatographic method for determining the water content of total particulate matter from mainstream cigarette smoke.

Q: What does it cover?

A: It covers sampling context (normally with ISO 4387), sample handling and a gas‑chromatographic analytical procedure (including calibration and result reporting) to quantify water in TPM; it also notes the Karl‑Fischer approach (ISO 10362‑2) as an alternative where GC is impractical.

Q: Who typically uses it?

A: Tobacco industry analytical labs, regulatory and independent testing laboratories, research organizations and QA/QC teams that measure constituents of cigarette smoke.

Q: Is it current or superseded?

A: As of its publication in July 2019, ISO 10362‑1:2019 is the current published edition (3rd edition) replacing earlier editions; the ISO catalogue lists the standard as published and notes periodic review/revision activity. Users should check their national subscription or ISO catalog for any subsequent revisions or drafts in development.

Q: Is it part of a series?

A: Yes — ISO 10362 is a multi‑part series covering water determination in cigarette smoke condensates/TPM; Part 1 covers the gas‑chromatographic method and Part 2 covers the Karl‑Fischer method.

Q: What are the key keywords?

A: Cigarettes; total particulate matter; mainstream smoke; water; gas chromatography; Karl‑Fischer; tobacco analysis; ISO 10362‑1.
