Compare SEM EDS/EDX detector compatibility, software, sample demonstrations and quotation scope before buying or upgrading a laboratory system in Bangladesh.
Buying an EDS system means specifying a detector, its microscope interface, analysis software and an agreed demonstration of the work your laboratory needs. A detector-area figure or a software name is not a complete purchasing specification. For a new SEM or an upgrade in Bangladesh, start with the existing instrument, representative samples and the results you need to report.
This guide covers purchasing and configuration. Use our EDS interpretation guide for measurement limitations, or the SEM selection guide when the microscope itself is also being purchased.
For an upgrade, provide the exact microscope model and serial number, available port drawings, installed detectors, stage and current computer/software details. Ask the microscope and EDS suppliers to confirm the proposed combination in writing. A spare port or an existing EDS installation does not establish that a different detector will fit.
| Configuration check | Ask the quotation to identify |
|---|---|
| Mechanical fit | Port adapter, insertion/retraction arrangement, working distance, sample tilt and collision clearances. |
| Detector geometry | The proposed detector position, collection geometry and possible shadowing for your holders and specimens. |
| Control and integration | Required imaging, beam and stage interfaces, computer specification, supported operating system and installation responsibilities. |
| Existing equipment | What is retained, replaced or removed, including any impact on other detectors, accessories and support arrangements. |
These are catalogue starting points, subject to current manufacturer compatibility and configuration review. SEM and TEM detector variants must be assessed for their intended platform.
| Starting point | Application to discuss | Evidence to request |
|---|---|---|
| Xplore | Routine SEM elemental analysis. | Demonstrate the required elements, quantification and mapping time on your samples. |
| Ultim Max Infinity | Higher-throughput mapping and demanding microanalysis. | Compare the quoted sensor size, useful throughput and energy resolution under stated conditions. |
| Ultim Extreme Infinity | Low-voltage work where low-energy sensitivity and geometry are central. | Confirm windowless-detector compatibility and demonstrate performance at the required working distance and beam conditions. |
| Hitachi TM-series AZtec EDS | EDS for a compatible tabletop microscope. | Name the exact TM model, detector and software package; identify optional mapping and automation functions. |

Oxford describes Xplore for routine SEM analysis, Ultim Max Infinity with multiple sensor sizes and Ultim Extreme Infinity for windowless, low-voltage analysis. Hitachi lists distinct AZtec configurations for its TM series. These descriptions establish product positioning, not suitability for every sample or microscope.
Energy resolution describes separation in the X-ray spectrum; it is not the spatial resolution of an elemental map. Ask which X-ray line, input/output count rates and processing settings support the quoted resolution. A maximum count rate and a best-resolution figure may describe different operating conditions. For low-energy work, request a relevant low-energy specification and a sample result.
Compare usable data collected in an agreed time at the same beam conditions, alongside spectrum quality, overlap handling and drift. Detector area alone cannot establish the result on your installed geometry. The acceptance demonstration should also reveal any damage or contamination that makes the chosen acquisition conditions unsuitable for the sample.
List the functions you actually need: point spectra, line scans, spectrum imaging, quantification, large-area mapping, particle analysis and data export. Oxford AZtecFeature addresses particle-analysis workflows; confirm the stage integration, modules and licences included. Our catalogue also includes AZtec analysis software. Ask for the currently offered version, supported workstation and upgrade terms.
For crystallographic orientation or phase work, discuss the EBSD detector and integration requirements separately. EDS software does not add an EBSD detector. Include offline processing seats, raw-data access, report exports, backups and operator training in the software discussion.
Request separate prices for the detector and electronics, microscope adapter/interface, workstation, software licences, reference materials, installation, training and service. Ask whether sample preparation equipment is needed. The offer should state currency, taxes or duties included, freight, delivery terms, quotation validity, payment schedule and site responsibilities.
Ask for warranty coverage and exclusions, response arrangements, software support and any planned maintenance charges. Pricing and delivery depend on the confirmed configuration and commercial terms; a generic detector price is not an installed-system budget. Use the same written scope when comparing offers.
Possibly, after model-specific mechanical, vacuum, electronics and software checks. Send the instrument details before requesting a firm retrofit price. Ask who will approve compatibility and carry out installation.
Compare demonstrated performance for the same sample and acquisition conditions. Include installed geometry, useful count rate, spectral quality and the software workflow; detector area is only one specification.
Some applications support useful light-element and trace analysis, as discussed in NIST research on quantitative EDS. Capability depends on the element, matrix, detector and method. Ask for detection-limit and uncertainty evidence relevant to your samples; do not assume a universal concentration threshold.
