Atomic Absorption Spectrophotometer Service | AAS Repairs & Service

AAS Down? The Fault Is Usually One of These

• Flame not igniting — gas box, igniter or safety interlock, almost never the lamp. Repairable at board level.
• Hollow-cathode lamp not recognised — turret contact or lamp-supply fault; we align and verify lamp energy after repair.
• Sensitivity far below the cookbook value — blocked nebuliser, misaligned burner or dirty optics; restored and verified with standard solutions.
• Graphite furnace temperature or tube errors — GFA contacts and controller service, with furnace temperature calibration.

Discontinued Model? We Still Service It

Varian/Agilent SpectrAA, AA240 and AA220, PerkinElmer AAnalyst 100 to 800, Shimadzu AA-6200 to AA-7000, GBC, Thermo, Analytik Jena — long after factory support ends, these platforms are our daily work. A University of Madras AAS written off with a "lamp fault" turned out to be a repairable board and is running today. We source spares for legacy models or repair at component level, and interface old instruments with new lab PCs.

Universities, soil-testing labs, pharma QC and metal industries across India use the service — on-site in South India, insured courier from everywhere else. An annual maintenance contract keeps flame and furnace systems audit-ready with scheduled sensitivity verification.

Describe the fault — flame, lamp, furnace or sensitivity — and we will tell you on the call what it likely is. Call +91 95000 10101, WhatsApp +91 95000 62555 or send the enquiry form — we reply the same working day.
