New headspace detection upgrade solution: 0ml sampling volume helps with small packaging quality control
Date: 2025-10-11Read: 37

Technological Innovation: CheckMate 4“dianfuSexual Upgrade

From "extraction" to "insertion", the new era of headspace analysis

In the pursuit of efficiency and safety in modern industry, the composition of headspace gas inside packaging directly determines the shelf life of food and the effectiveness of drugs. Whether it's the rich aroma of coffee capsules or the stability of drugs in penicillin bottles, precise control of the oxygen content inside the packaging is essential.


However, traditional headspace analysis equipment often requires extracting a certain amount of gas sample, which is not only difficult to operate for small volume headspace packaging (such as medicine bottles, coffee capsules, blister packaging, etc.), but also may affect the accuracy of results due to sample loss.


In response to the pain points in this industry, Dansensor has officially launched the newly upgraded CheckMate 4 headspace gas analyzer. The core of this upgrade lies in its small volume (SV) optical sensor technology that does not require gas sampling, achieving zero sampling, accurate, and efficient detection of various sizes of packaging, especially micro headspace packaging.

Traditional headspace analysis is like a "blood test", while CheckMate 4 SV version implements "minimally invasive probe detection". Its revolution lies in:


1. True zero sample size:Using a unique optical sensor probe pen (divided into A/B needles), the sensor is directly placed inside the packaging for measurement without the need to extract headspace gas. This not only avoids the pressure imbalance inside and outside the packaging caused by sampling, but also solves the problem of insufficient sample size in extremely small headspace environments.

2 Fast Response, Get in One Second: Pick upThe sample analysis time has been reduced to an astonishing 1 second, greatly improving the efficiency of online sampling and aligning with the quality control rhythm of high-speed production lines.

3 J highAccuracy and Resolution:Within the measurement range of 0-100%, the resolution is as high as 0.001%, ensuring a precision of ± 0.02% even in ultra-low oxygen environments below 1%, providing reliable data support for shelf life research and quality control.

Application Panorama: From Modified Atmosphere Packaging for Food to Aseptic Packaging for Drugs

Multi purpose, fully covering quality control scenarios

CheckMate 4 offers multiple sensor configurations (standard O2/CO2, small capacity optical O2) to flexibly meet the needs of different industries.

1. Food industry:

Coffee capsules and tea bags: Micro damage probes can accurately penetrate the capsules, quickly detect residual oxygen levels without losing flavor substances, and ensure the best flavor of the product.

Modified Atmosphere Packaging Food (Cold Fresh Meat, Fresh Fruit Cut): Standard models can simultaneously measure O2 and CO2, accurately verifying whether the packaging gas ratio meets the standard and effectively extending the shelf life of food.

Powder products: Monitor the oxygen in the packaging headspace to prevent oxidation and deterioration, and protect the taste and nutrition of the product.

2 Pharmaceutical industry:

Penicillin and Ampoule Bottles: The surgical knife tip probe pen places the oxygen sensor into the testing packaging for precise detection, without the need to extract gas samples. The stability of protein drugs and vaccines is crucial.

Bubble wrap packaging: The needle tip probe pen can be accurately inserted into the gap of the bubble wrap to avoid puncturing the drug, ensuring safe testing and accurate data.


Intelligent experience: simplifying complex digital workflows

Not only precision, but also intelligence

CheckMate 4 is not only a gas analyzer, but also an intelligent data terminal:

1. Intuitive touch and permission management: Multi language touch screen simplifies operations, and personal user login function ensures data security and traceable operations.

2 barcode scanning quick call: can be used in conjunction with barcode scanners, scanning product barcodes can automatically call the corresponding detection program, eliminating human setting errors.

3. Massive data and seamless integration: The device can store up to 1000000 test results and export CSV data in real-time through USB or LAN, easily integrating with your system or CheckMate 4 PC software, providing a complete data chain for quality auditing and process optimization.
