Featuring longitudinal Zeeman background correction, a transverse-heated graphite furnace, and an integrated flame and graphite furnace design, the AA-7090 supports a wide range of analytical applications in research, industrial testing, and quality control laboratories.\u003cbr\u003eThe instrument incorporates an advanced optical system with an 1800 lines\/mm diffraction grating, a compact optical path, and automated switching between flame and graphite furnace atomization modes in less than two seconds. Its continuously adjustable magnetic field helps optimize background correction for different elements, while automated wavelength positioning, lamp selection, slit adjustment, and lamp-current optimization simplify routine operation.\u003cbr\u003eThe AA-7090 can analyze more than 70 elements, according to the manufacturer, and supports multiple analytical methods, including flame absorption, flame emission, graphite furnace, and hydride analysis. Its software provides calibration, concentration calculations, quality-control checks, data management, and report generation.\u003c\/p\u003e\n\n\n\u003cstyle\u003e\n  .labtech-specs {\n    width: 100%;\n    border-collapse: collapse;\n    font-family: Arial, sans-serif;\n    font-size: 14px;\n    color: #333333;\n    margin: 20px 0;\n    background: #ffffff;\n  }\n\n  .labtech-specs caption {\n    text-align: left;\n    font-size: 22px;\n    font-weight: 700;\n    color: #164b78;\n    padding-bottom: 14px;\n  }\n\n  .labtech-specs th,\n  .labtech-specs td {\n    border: 1px solid #d9e1e8;\n    padding: 12px 16px;\n    text-align: left;\n    vertical-align: top;\n    line-height: 1.6;\n  }\n\n  .labtech-specs thead th {\n    background: #164b78;\n    color: #ffffff;\n    font-weight: 600;\n  }\n\n  .labtech-specs tbody tr:nth-child(even) {\n    background: #f3f7fa;\n  }\n\n  .labtech-specs tbody tr:hover {\n    background: #e8f3fa;\n  }\n\n  .labtech-specs tbody td:first-child {\n    width: 42%;\n    font-weight: 600;\n    color: #164b78;\n  }\n\n  @media (max-width: 600px) {\n    .labtech-specs {\n      font-size: 12px;\n    }\n\n    .labtech-specs th,\n    .labtech-specs td {\n      padding: 8px;\n      overflow-wrap: anywhere;\n    }\n\n    .labtech-specs caption {\n      font-size: 19px;\n    }\n  }\n\u003c\/style\u003e\n\n\u003ctable class=\"labtech-specs\"\u003e\n  \u003ccaption\u003eTechnical Specifications – EWAI AA-7090\u003c\/caption\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth scope=\"col\"\u003eSpecification\u003c\/th\u003e\n      \u003cth scope=\"col\"\u003eAA-7090\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eInstrument Type\u003c\/td\u003e\n      \u003ctd\u003eZeeman Atomic Absorption Spectrophotometer\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eWavelength Range\u003c\/td\u003e\n      \u003ctd\u003e190–900 nm\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eWavelength Accuracy\u003c\/td\u003e\n      \u003ctd\u003e±0.1 nm\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eWavelength Repeatability\u003c\/td\u003e\n      \u003ctd\u003e≤ 0.05 nm\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMonochromator\u003c\/td\u003e\n      \u003ctd\u003eCzerny–Turner grating monochromator\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eDiffraction Grating\u003c\/td\u003e\n      \u003ctd\u003e1800 lines\/mm\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBlazing Wavelength\u003c\/td\u003e\n      \u003ctd\u003e250 nm\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSpectral Bandwidth\u003c\/td\u003e\n      \u003ctd\u003e0.1, 0.2, 0.4, 1.0, 2.0 nm;
