kroh-muh-tuh-GRAF-ik
/kɹoʊ.mə.təˈɡræf.ɪk/
chromatographic is pronounced kroh-muh-tuh-GRAF-ik (/kɹoʊ.mə.təˈɡræf.ɪk/). It has five syllables (chro-ma-to-graph-ic), with the stress on "graph". Chromatographic refers to methods or techniques used in chromatography, where components are separated based on their movement through a medium under the influence of a solvent. The term combines ‘chromato-’ (color or chroma) with ‘-graphic’ (writing or recording), describing processes that separate and record components in a mixture by their different affinities. In practice, it often describes techniques like thin-layer or column chromatography that rely on differential migration.

"They discussed chromatographic efficiency and plate height to optimize the procedure."
Accent on the third syllable: chro-MA- to- GRAPH- ic. IPA US: krəˌmæ təˈɡræfɪk. UK: krəˌmætəˈɡræfɪk. AU: krəˌmætəˈɡræfɪk. Break into syllables: chro-ma-to-graphic, with primary stress on -graphic (-gra-). Ensure the vowel in -mat- is a lax schwa-like /ə/ in unstressed positions; the -graphic suffix carries the strong stress. You’ll start with a soft /kr/ blend, then a mid-central vowel, and finish with a crisp /ˈɡræfɪk/.
Common errors: misplacing stress (thinking stress is on -mat- rather than -graphic); mispronouncing the third syllable as /ə/ vs /æ/ in -mat-; and trailing “graphic” as /ɡræfɪk/ with a weak final consonant. Correction: keep primary stress on the -graphic part: /-ˈɡræfɪk/; use a clear /æ/ in the -ma- before -to- when the syllable is stressed, and maintain a strong, aspirated /k/ at the end. Practice slow: /krəˌmætəˈɡræfɪk/ and then speed up while preserving the rhythm.
US/UK/AU share the /krəˌmætəˈɡræfɪk/ skeleton but vowel quality shifts slightly: US tends toward a rhotacized or rhotic /ɹ/ influence in the first syllable cluster; UK leans toward a more clipped /ə/ in unstressed schwa and a slightly tighter /æ/ in -ma-; AU tends to a broader /ɐ/ or /ə/ in unstressed positions with slightly longer vowels overall. Stress placement remains on -graphic, with similar final /ɡræfɪk/. In slow careful speech, these differences are subtle but audible in syllable length and vowel openness.
Difficulties stem from multi-syllable length, the -graphic suffix, and shifting vowel qualities across syllables. The sequence /ˌmætə-ˈɡræfɪk/ requires maintaining a clear boundary between -ta- and -graphic while not flattening the vowels. The cluster /kr/ at start plus the medial schwas can cause swallowing or reduction. Also, the final stressed -graphic part demands a precise /ɡræ/ onset followed by a crisp /fɪk/. Practice with careful IPA-guided drills helps prevent skippable vowels and consonant merges.
Focus on the transition between the -to- and -graphic syllables. Many speakers blur /tə/ and /ˈɡræ/ leading to /təˈɡræ/ without a clear boundary. Practice with a deliberate pause: krə-mæ-tə-ˈɡræfɪk, then gradually connect while maintaining the boundary. Visualize the word as three parts: chro-ma-to-graphic, ensuring each part has its own timing. Using an audio cue, like tapping the syllable boundaries, helps lock in the rhythm.

Chromatographic derives from the Latinized form of the Greek words chroma (color) and ta- (a through-form) combined with the suffix -graphic (written or described). The root chroma signals color or pigment, reflecting chromatography’s historical use to separate colored components. The term coalesced in the 19th and 20th centuries as chromatography evolved from a family of color-based separation techniques (colorimetry, pigment study) into a general method for separating compounds by differential partitioning. Early 20th-century scientists like Mikhail Tsvet pioneered chromatography, and subsequent refinements introduced modern variants (paper, thin-layer, gas, high-performance liquid chromatography). The adjective chromatographic emerged to describe anything pertaining to or employing chromatography, especially methods where separation is manifest in recorded signals or chromatograms. First known uses appear in scientific literature around the 1900s–1920s as analytical chemists formalized the language of separation science; the term gradually acquired the broader sense of “relating to chromatography” in both techniques and instrumentation. Contemporary usage spans instrumental separations (HPLC, GC) and qualitative/quantitative analyses in chemistry, biology, and environmental science, always marking a record of solute movement through a stationary phase under a mobile phase’s influence.
