Read Results -> Match Specs -> Flag Out-of-Spec -> Draft Certificate -> Route for Approval

Certificate-to-Spec Matcher and Release Drafter

The Certificate-to-Spec Matcher reads a batch's analytical results and checks every parameter against each customer's agreed specification, since one batch is often sold to many customers with different limits. It flags anything out of spec and drafts the certificate of analysis in each customer's format. Your quality approver reviews the matches and approves before anything is sent.

The Problem

One batch, forty specs, all matched by hand.

Batch 24-1187 clears QC with a full analytical panel. It is committed to six customers, and each one signed a different specification: one caps moisture at 0.30 percent, another at 0.50, a third does not mention it. Your customer service coordinator opens six spec sheets and the LIMS report side by side, checks every parameter against every limit, and retypes the passing values into six different certificate templates. One transposed decimal and the wrong certificate goes out the door.

What Changes

Match every parameter to every spec, in one pass.

The agent reads the analytical panel once and checks it against every customer's agreed limits in one pass. It marks pass or fail per parameter per customer, calls out anything out of spec, and drafts each certificate in the format that customer expects. The cross-checking and retyping across formats are gone, and every matched value is traceable.

Humans stay in control: the agent matches and drafts, your quality approver clears every out-of-spec flag and approves each certificate. The batch is released and the certificate sent only by a person.

WHAT YOUR TEAM PROVIDES ONCE

LIMS or ERP results - the batch analytical panel to check
Customer specification store - the agreed limits for each account
Product master - parameter names, units, and methods
Pass or fail per parameter per customer - the full matching result
Drafted customer certificate - in each customer's format, ready to approve

What happens day-to-day: a batch clears QC, the agent reads the analytical panel, checks every parameter against each customer's agreed limits, flags anything out of spec, and drafts a certificate in each customer's format. Your quality approver reviews the matches, clears the out-of-spec flags, and approves before anything is sent.

WITHOUT PMS API

Without an API, the agent works from a LIMS result export and a spec workbook per customer. It matches from the CSV and drafts certificates as documents, and a person moves the approved certificate into the customer's system by hand.

WITH PMS API

When LIMS and the spec store expose an API, the agent reads results and every committed customer's limits on posting, matches automatically, and drafts each certificate into its template. Best experience.

For the person who wants to build this agent step by step. Each node below maps to an n8n workflow node.

TRIGGERNode 1

Trigger - watch LIMS for results

Webhook or poll on batch result posting. Filter for final, approved analytical panels only.

Output: Batch id and result set

APINode 2

Results Pull - read the panel

Query LIMS or ERP by batch id for every parameter, value, unit, and method.

Output: Analytical results array

APINode 3

Spec Load - read customer specs

Look up which customers the batch is committed to, then load each account's agreed specification.

Output: Per-customer limit sets

LLMNode 4

LLM - match parameters to specs

Pass the results and each customer's limits. Ask for a pass or fail per parameter per customer and an overall result, with out-of-spec values called out.

Output: Match result per customer

You are checking batch analytical results against customer specifications. Compare only the parameters given. Do not invent limits.

Batch results:
{batch_results}

Customer specifications:
{customer_specs}

Product master units and methods:
{product_master}

For each customer, give a pass or fail per parameter and an overall result. Call out every value that falls outside its limit. Respond ONLY with valid JSON. No explanation.

INPUT

Batch 24-1187 with assay 99.4% and moisture 0.28%, checked against two customers: one caps moisture at 0.30%, the other at 0.20%.

OUTPUT

{"customers":[{"customer":"Account 4471","result":"pass","parameters":[{"name":"Assay","value":99.4,"unit":"%","limit_low":99.0,"limit_high":100.5,"status":"pass"},{"name":"Moisture","value":0.28,"unit":"%","limit_high":0.30,"status":"pass"}]},{"customer":"Account 8820","result":"fail","parameters":[{"name":"Moisture","value":0.28,"unit":"%","limit_high":0.20,"status":"fail"}]}]}

DECISIONNode 5

Decision - route by result

Passing customers go to certificate drafting. Out-of-spec customers are held and flagged for quality review before any draft.

Output: Customers split pass or hold

ACTIONNode 6

Action - draft certificate and route

Fill each passing customer's certificate template with the matched values and create a quality approval task. Nothing sends without approval.

Output: Drafted certificates and approval tasks

MVP vs Advanced — Where To Start

MVP — START HERE

Start with one product and top customers
Pull results from a LIMS export
Enter each customer's limits in one workbook
Run the match LLM node per parameter
Draft certificates from one shared template
Quality approves and sends by hand

ADVANCED — ADD LATER

=+ Connect the LIMS API on result posting
=+ Load specs live from the spec store
=+ Support each customer's certificate format
=+ Auto-hold and escalate out-of-spec items
=+ Track which spec version was matched
=+ Flag when a new spec is tighter than the batch
