It features a double-beam total-reflection optical system with automatic baseline compensation and real-time lamp drift correction to support stable analytical performance.\u003cbr\u003eThe AA-7050D automates key operations, including zero return, wavelength scanning, lamp positioning, mirror adjustment, and energy balancing according to the selected element and analytical method. Its computer-controlled eight-lamp turret enables automatic lamp selection, while six automatic spectral bandwidth settings provide flexibility for different analytical requirements.\u003cbr\u003eWith deuterium-lamp and self-reversal background correction methods, a high-sensitivity photomultiplier tube, and flame emission capability, the AA-7050D supports a broad range of laboratory testing applications. EWAI states that the instrument can analyze more than 70 elements.\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: #263746;\n  margin: 20px 0;\n  background: #ffffff;\n}\n.labtech-specs caption {\n  text-align: left;\n  font-size: 20px;\n  font-weight: 700;\n  color: #164b78;\n  padding: 12px 0;\n}\n.labtech-specs th {\n  background: #164b78;\n  color: #ffffff;\n  text-align: left;\n  padding: 13px 15px;\n  border: 1px solid #164b78;\n}\n.labtech-specs td {\n  padding: 11px 15px;\n  border: 1px solid #d9e1e8;\n  vertical-align: top;\n  line-height: 1.5;\n}\n.labtech-specs tbody tr:nth-child(even) {\n  background: #f3f7fa;\n}\n.labtech-specs tbody tr:hover {\n  background: #e8f3fa;\n}\n.labtech-specs td:first-child {\n  width: 36%;\n  font-weight: 600;\n  color: #164b78;\n}\n@media screen and (max-width: 600px) {\n  .labtech-specs {\n    font-size: 12px;\n  }\n  .labtech-specs th,\n  .labtech-specs td {\n    padding: 9px 8px;\n  }\n}\n\u003c\/style\u003e\n\n\u003ctable class=\"labtech-specs\"\u003e\n  \u003ccaption\u003eEWAI AA-7050D Atomic Absorption Spectrophotometer – Specifications\u003c\/caption\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eParameter\u003c\/th\u003e\n      \u003cth\u003eSpecification\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eModel\u003c\/td\u003e\n      \u003ctd\u003eAA-7050D\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eOptical System\u003c\/td\u003e\n      \u003ctd\u003eDouble-beam total reflection optical system\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eElement Analysis\u003c\/td\u003e\n      \u003ctd\u003eCapable of analyzing more than 70 elements\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSpectral Bandwidth\u003c\/td\u003e\n      \u003ctd\u003eSix automatic slit settings: 0.1, 0.2, 0.4, 0.7, 1.0 and 2.0 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\u003eSpectral Resolution\u003c\/td\u003e\n      \u003ctd\u003eBetter than 0.1 nm\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eLamp Turret\u003c\/td\u003e\n      \u003ctd\u003eComputer-controlled 8-lamp turret\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eLamp Operation\u003c\/td\u003e\n      \u003ctd\u003eAutomatic preheating of the next element lamp;
