A Practical Guide to International Instrument Inquiries

A complete instrument inquiry helps the supplier prepare a useful proposal. Include the seven items below to reduce follow-up questions.

What a supplier can and cannot infer

Country and product information alone may not define the required configuration. Include voltage, water quality, language, service location and the measurement parameters.

The seven items

1. Country and site, including the electrical supply and whether it is stable.
2. The parameters to be measured, with units and ranges.
3. The sample matrix and how it is prepared.
4. Daily and peak sample count.
5. The method or reference the laboratory must follow.
6. The services available: water purity, gas, ventilation, bench space.
7. The expected service route: who installs, who trains, which parts are stocked.

What each item decides

Item	What it decides in the proposal
Country and supply	Voltage variant, plug, documentation language
Parameters and ranges	Instrument group and model level
Matrix and preparation	Accessories, digestion, filtration, cell type
Sample count	Throughput, automation, number of channels
Method reference	Verification scope and consumables list
Site services	Whether the configuration can be installed at all
Service route	Spare-parts stock, training depth, warranty terms

The two items most often missing

The sample count and the site services. Without the count, the supplier cannot tell whether the laboratory needs one channel or two, or whether an autosampler is justified. Without the services, the supplier cannot tell whether the proposed configuration will run at all — a laboratory without adequate water purity cannot operate an ion chromatograph, however good the instrument.

What happens when the brief is complete

A complete brief allows the supplier to propose a configuration with accessories, consumables, installation, training and service arrangements for internal review.

Keeping the inquiry short

Seven items fit on one page. A short, specific inquiry gets a faster and more accurate answer than a long one describing the laboratory’s history. Write the seven, attach the specification if there is one, and ask two questions: what would you propose, and what would you need to confirm on site.
