Solid State Gas Sensors
Products and Services
Synkera's products are based on nano- and
microstructured materials and advanced methods for their
integration into functional devices. We offer three
main product groups:
The
first is a broad group of chemical sensors
and related devices. Synkera's sensor
technology is bridging the gap between the low
cost of traditional solid-state sensors and
the performance of liquid electrolyte
electrochemical sensors.
The
second product group is comprised of membranes
for filtration and separation in gases and liquids and
related applications. Our membranes are based on self-organized
nanoporous ceramic that supports highly controllable
nanoscale morphology and composition, enabling high
performance, reliable and cost-effective solutions in a
diverse range of applications.
The
third product group includes a broad range of NanoCeramic-based
offerings with performance and benefits engineered at
the nano/microscale. These include nanotemplates,
substrates for bioanalysis, ceramic microcomponents,
functional coatings and nanocomposites.
Electronic Modules
Synkera now provides two
types of modules for testing and evaluation of our
various sensor product lines:
Our latest
MikroKera™ Ultra Module (P/N 9100) features
all-digital input and output, and even wireless
connection by Bluetooth. This module can be used for
quick and easy setup and evaluation of our UltraKera™
sensor product line (module purchase includes 1 sensor).
Our original set of electronic modules, encompassing P/N
901 to 917, feature analog input and output, and can be
used to operate both our
ProKera™ and
MikroKera™ sensors. These modules require a 9-12
VDC input and provide a 0-5 VDC output. These modules
allow for adjusting the input voltage to the heater,
zeroing the sensor, and setting gain. To place an order

Ceramic Membranes
Synkera's
largest 11" x 18" AAO membrane with aluminum rim.
Synkera offers three different types of membranes:
UniKera™ Standard,
UniKera™ UF and
nanocomposite. Unique features and
performance of these products are derived from the
controllable nanoscale morphology and composition of the
active layer(s), as well as chemical and mechanical
properties of anodic
aluminum oxide. These membranes are produced using
our unique capabilities in extremely high precision
nanoscale engineering of materials architecture and
composition, following strict quality-control
procedures.
Synkera offers a range of standard products, as well as
many custom options for each membrane type. Please
follow the links below for further details or go
directly to the quote/info
forms to request a quote or to place an order.
Our
symmetric membranes feature uniform and aligned
cylindrical nanopores, ensuring consistent pore
diameter and pore density throughout the thickness of
the membrane.
Our
monolithic asymmetric membranes feature a
support layer with large pores and a
very thin (sub-0.5 µm) active layer with pores
tunable in the 5-200 nm range. This allows for precise
size-based separation, while maintaining high permeance
and low fouling. These features enable significant
performance benefits in liquid separation, such as
microfiltration, ultrafiltration and nanofiltration.
Our
nanocomposite membranes feature very thin
nanocomposite active layers intimately embedded
within the pores of anodic alumina to enable high
permeance and selectivity to target molecules and
outstanding reliability in operating conditions.
UniKera Standard Membranes
Pricing
Synkera offers symmetric monodisperse nanoporous ceramic
membranes that are produced from nanoporous anodic
aluminum oxide (AAO). This type of membrane features
a symmetrical nanoporous architecture with uniform
cylindrical pores penetrating the entire thickness of
the membrane, and are characterized by a high degree of
pore ordering and narrow pore size distribution
(standard deviation is typically better than 8%, and in
some cases is as low as 5%).
Synkera's symmetric membranes have superior mechanical
and thermal stability far exceeding that of anodic
alumina membranes from other suppliers. As-prepared AAO
membranes are amorphous, but could be converted to
nanocrystalline gamma and alpha-alumina phases which
further enhances the membrane's chemical and thermal
stability. Synkera offers several membrane
heat-treatment options for operating temperatures up to
1000°C.
The range of currently available membrane specifications
is summarized in the table below. We maintain an
inventory of membranes with standard specifications.
Most of our ceramic membranes could be ordered with a
pore diameter in the range from 10 to 150 nm, and the
thickness from 15 to 100 microns. For more details on
this product, please see the AAO
Technology Profile.

Most of our AAO nanotemplates and nanoporous
membranes could be ordered with pore diameter in 10-100
nm range. They are characterized high degree or pore
ordering, narrow pore size distribution (standard
deviation is typically better then 10%, and in some
cases as low as 5%), as well as uniform pore diameter
across the entire AAO thickness. For free-standing
nanotemplates, standard heat-treatment options include
annealing of the originally amorphous AAO to
nanocrystalline gamma or alpha-alumina phase, which
further enhances nanotemplate's chemical and thermal
stability.

Demand for robust and resilient microcomponents
increases with the continuous trend towards
miniaturization. Many existing and new applications
require microcomponents from refractory materials to
obtain requires mechanical properties and ensure
stability in harsh environments. Although silicon
carbide, silicon nitride, and sapphire have been
identified as candidates for this type of MEMS,
combination of high cost, poor manufacturability, and
very limited designs stimulates the development of new
technologies.
