Sample Lifecycle & QC

Traceable, Transparent Testing Process

From sample intake and barcode registration through dual-tier quality control and certified report generation, every assay follows a documented, audit-ready workflow.

Workflow & Traceability

A Simple, Transparent Testing Process

Every sample at NERO Labs follows a rigorous, traceable 5-stage lifecycle from collection to analytical test report delivery.

STAGE 01

Sample Collection

Sample Collection will be done as per ISO, IS, APHA, AOAC and as per Customer Specification

✓ Proper preservation container check • Temperature cold-chain log • Chain-of-custody verification
STAGE 02

Sample Submission

Receipt of physical water, food, soil, mineral or fertilizer samples with chain-of-custody documentation.

✓ Proper preservation container check • Chain-of-custody verification
STAGE 03

Sample Registration

Unique barcode logging, laboratory information management system (LIMS) intake and cold/dark storage.

✓ Barcode assignment & tagging • LIMS intake entry • Controlled cold storage allocation
STAGE 04

Laboratory Analysis

High-precision instrument testing (spectrometry, chromatography, microbiological culturing) by analysts.

✓ Daily instrument calibration check • CRM matrix verification • Standardized SOP testing
STAGE 05

Quality Verification

Dual-tier data review, blank and duplicate spike verification, and quality audit sign-off.

✓ Blank and duplicate spike check • QA manager independent sign-off • Statistical outlier evaluation
STAGE 06

Test Report

Generation of dependable, clearly structured digital test certificates with tamper-evident authentication.

✓ Digital cryptographic signature • Tamper-evident certificate generation • Customer portal delivery
Logistics & Preparation

Sample Submission & test Packaging Guidelines

Ensuring proper collection and preservation is critical for analytical accuracy. Follow these standard steps prior to dispatch.

Step 01

Sample Preservation

Use clean, non-leaching amber glass or high-density polyethylene (HDPE) containers. Keep temperature-sensitive samples chilled at 2-6°C.

Step 02

Chain of Custody (CoC) Form

Accompany every shipment with a signed Chain-of-Custody document indicating sampling date, location, target parameters, and client details.

Step 03

Tamper-Evident Sealing

Apply serialized security seals to container caps to guarantee sample integrity from dispatch until intake at our analytical receiving dock.

Step 04

Courier / Drop-off Tracking

Send tracking information to our laboratory sample coordinators or hand-deliver directly to our central sample collection window.

Dual-Tier Quality Verification

Every Result Is Checked Twice Before Sign-Off

Our laboratory protocol dictates that no test certificate is finalized until the primary analyst’s raw data is independently checked against certified calibration curves and blank-spike controls by our Quality Assurance manager.
