Gas Adsorption Gas Separation Vapor Series ● Simultaneously perform vapor adsorption, specific surface area. ● Analyze up to 2 samples at once (1 vapor, 1 micropore). ● Configurable with 1 or 2 analysis stations to meet varying lab needs.

The AMI Vapor Series instruments are precision volumetric analysers designed for advanced vapor and gas sorption characterisation. These systems are ideal for analysing adsorption isotherms, surface area, pore size distributions, and gas selectivity, using noncorrosive and safe adsorbates under controlled conditions.

Typical adsorbates include water vapor, benzene, carbon monoxide, ammonia, and other non-corrosive gases and vapors at room temperature.

Key Features

KEY FUNCTIONS

Vapor Adsorption Isotherms: Evaluate adsorption behavior over a range of relative pressures for various vapor species.

Gas Selectivity & Capacity: Determine selective adsorption characteristics and quantify sorption capacity.

Surface Area & Pore Size Distribution: Low-temperature nitrogen adsorption method for BET and BJH analysis.

Automated Vapor Generation and Delivery

Fully Automated Vapor Source Module:
Eliminates manual handling. Ensures high-purity vapor via software-controlled delivery.
Vapor Source Thermostatic Control:
Integrated water bath under software control for consistent vapor temperature and stability.

Advanced Analysis Capabilities

Fully Automated Vapor Source Module:
High-precision pressure transducers (10, 100, 1000 torr) for accurate measurements across a wide pressure range
High-vacuum corrosion-resistant solenoid valves.
Comprehensive software automation for sorption analysis and reporting.

Precision Vacuum Control

Ultra-High Vacuum System:
Includes a turbo molecular pump to achieve pressures down to 10-7–10-8 Pa, optimizing desorption and system cleanliness.
Cold Trap System (Dual Stage):
Standard dual cold traps minimize vapor back streaming and protect the vacuum pump, extending system longevity.

Thermal Stability and Sample Conditioning

Thermostated Analysis System: Built with corrosion-resistant materials
heated pathways to avoid condensation. Temperature range: ambient to 50°C.
Sample Temperature Control Options:
Dewar Flask: 77 K (liquid nitrogen)
Water Bath (Optional): -10°C to 95°C
CryoTune Cold Bath (Optional):

Outstanding service

I have been using Meritics for a number of years and they always provide outstanding service and support.
They have a rapid response turnarounds and are very knowledgeable of the techniques and products they provide.

LeanneB-375

Good service, very helpful

We use Meritics for the PM service and installation of all our FlowCams . Megan has been coming to our site for a number of years. She is very efficient in her work, but most of all Megan is very helpful. We have had issues with one of instruments after the install and Megan did her utmost to try and solve it while on site, even though it wasn’t solved Megan has been in contact with the supplier of the instrument to try and solve this problem for us.

Job done in a friendly manner

Booking engineer visits is always easy. David Lowe, Meritics engineer is always very friendly.

5 Stars

Excellent service from an excellent company. Would recommend them to anyone.

BarryH-480

Good Service

David, our service engineer as usual was good at communicating and setting up the recent service appointment, he arrived on time, did the service promptly and informed me of any problems. Friendly and helpful

TomA-446

Superb and prompt service

I have used this company through the laboratory I work for frequently. We specialise in soil analysis, and Meritics were chosen as they have extensive knowledge of the instruments we use. We have several laser particle diffraction analysers with a service contract, and service is always very prompt and meticulous….

JamesG-2483

Good experience over two years

Meritics have covered the annual servicing of our Multisizer 4e instrument since we purchased it from them just over two years ago. The application scientist who performed the servicing was friendly, knowledgeable, and extremely helpful, happily answering a barrage of questions about how best to use and maintain the instrument. All my interactions with Meritics staff have been positive. I would happily recommend them.

RajG-62

Fully committed to customer service

Service second to none, both units serviced and all questions answers by engineer while on site.

RichardA-786

Highly recommend Meritics for equipment purchases and aftercare services

After owning one of our instruments for over 8 Years which was purchased from Meritics, it suffered its first breakdown. Upon contacting Meritics, I was instantly put through to an engineer who was very helpful. Upon inspection of the manual, it was decided that it would be more cost effective to have a Meritics engineer visit. The Meritics staff were very communicative and kept me up to date.

Excellent Service

Lovely, friendly and extremely helpful. David and his team are always on call with advise and are very easy to work with and are always happy to help.

Professional

Friendly and collaborative staff, provided a very good service.

SamK-403

Professional, Customer-oriented, fast service

We had issues with one of the aperture tubes provided by Meritics on a Friday afternoon, while very pressed for a review deadline. Meritics handled our inquiries very fast and professionally and helped us out by shipping us their spare tube to use in the mean time free of charge, while we waited for our new tube to arrive. Communication was very pleasant.

VeerleB

Very helpful and prompt

I emailed for some technical help and also to get some spares and both the engineer (David) and purchasing (Sophie) were very prompt to respond and helpful. We do have a service contract but I appreciated being able to email the engineer directly.

AlexH-474

Excellent Service

Used Meritics to conduct particle size distribution by laser diffraction. Service as last time, is very quick, well priced and professional.

I would highly recommend

GavinR-101

Excellent and Friendly Service

Always a pleasure to deal with the people at Meritics Ltd. They understand the importance of our work and the fact that our research projects have deadlines that need to be met. Consequently, problems are dealt with very quickly and professionally and they are willing to go that one step further to make sure their supply chain problems don’t become our problems. Thank you to the team for their support. It is greatly appreciated.
