Questions that come up before an order

Because the number depends on four things that are not on the page: the isomer and its ratio, the packing
size, the documentation set, and the lead time you can accept. A catalogue price for a semiochemical is
either a placeholder or a quote for a grade nobody asked for. Send the specification and the price comes
back with the packing options attached.

Development quantities below the standard 1 kg pack are available for blend trials and for laboratory
work, so a programme can test a ratio before committing to a drum. The exact split is confirmed in the
quotation, because the packing that makes sense for a 200-trap grid is different from the one that makes
sense for a single-season trial.

Yes — most orders are blends. What matters is who sets the ratio: if your programme already has one, we
formulate to it and state the delivered composition; if the programme is being designed, the ratio is
worked out from the target complex, the trap type and the flight window, then fixed in writing before
anything is packed.

The certificate of analysis states assay plus the isomeric composition, with the chromatogram that
produced both. It matters because the minor isomer is a different semiochemical: a lure can contain the
right compound at the right loading and still underperform if the (E)/(Z) balance is off. We would rather
state an unfashionable number than imply a purity the lot does not have.

Certificate of analysis, GC trace, safety data sheet and packing list — per lot. An isomer statement can
be added where a specification calls for it, and method detail is available when a tender asks for the
chromatographic conditions rather than just the result.

Yes. Send the specification and the tender reference; we respond in the same structure — compound, CAS,
isomer, assay basis, packing, documentation, delivery — so the bid can be assessed line by line. Where a
specified isomer or grade is not held, we say so rather than substituting quietly.

Lead time is confirmed at quotation because it depends on whether the material is held as stock, whether
the isomer must be made, and how the consignment is documented. The planning point is simpler: order
before the flight season, not during it. A trap grid that starts two weeks late reads as a low population
rather than a late start.

Cool, dry and dark: sealed under inert gas at −20 °C for anything held beyond one season, with
containers brought to room temperature before opening so condensation does not enter the material.
Formulated lures age faster than neat compounds — a lure stored warm over winter is a different lure by
spring, which is why lot dates belong in the programme record.

The catalogue is about the chemistry. Trap type and dispenser choice are part of the programme
discussion, because the loading that works on a rubber septum is wrong on a membrane dispenser, and the
reverse. We will specify the dispenser a blend is designed for rather than sell one that happens to be in
stock.

Send the species, the blend you are working from and the quantity. Most gaps are one of three things: a
component we hold under a different name, an isomer we would need to make, or a compound that is simply
not commercially available at the purity a lure needs. The third answer is the useful one to get early.

Consignments are quoted with the documentation the destination requires, and the SDS is issued in the
language that destination expects. Plant-protection and permit requirements sit with the importer, but we
will supply the technical documentation those applications ask for — that is usually where an import
stalls.

Buying against a specification rather than a price list: the same isomer, the same assay basis, the same
certificate layout, and a retained sample from each lot. Programmes that compare trap catch across years
are effectively comparing lots, so the boring consistency is the feature.
