HiQ ® specialty gas program – Biotech, chemical, petrochemical & pharmaceutical
Preface
In today’s rapidly changing environment, there is a constant stream of new products becoming available. Some
products like pharmaceuticals are developed to increase the quality of life of patients. Or in the case of the biotech
industry, to develop biodegradable materials to reduce or even eradicate waste. The chemical industry is looking into
how to convert waste or polluted products into raw materials to increase the life span of products. The petrochemical
industry is searching for more efficient production methods, since many of its raw material resources are not
renewable.
Time to market is decreasing rapidly in combination with shorter lifecycles for new products. This is forcing industry today to focus
continuously on new developments and flexible ways of working to assure their success.
Customers are demanding, even requiring ready solutions. This is challenging us perpetually to adapt and refine our offerings in order
to satisfy current needs.
And that is exactly what we have done with the HiQ

® concept. HiQ ® products continue to revolutionize how specialty gas is presented
to the market.
Clear products, and industry-specific information for each of the market segments. The HiQ ® product range is customer-oriented to
the highest degree. It challenges us perpetually to offer the
most intelligent solutions that allow customers to work efficiently
and economically. We offer complete solutions.
But we also go further by providing additional technical information
such as gas properties and clear recommendations
concerning the required equipment. And we do not
limit ourselves to the products offered here. We can provide
additional services such as certification or customerspecific
products to put you in pole position. All you need
to do is contact us and let us together find an innovative
solution to your needs.
The HiQ ® concept stands quite simply for
‘everything from a single source’.
HiQ ® . It’s our word.
All gas products are quality controlled. When applicable,
an analysis certificate is included in the product. If not included,
it can be requested separately. Please, check with
your local Linde office to find out what is applicable for the
products you order.
• Under the heading ‘impurities’ the maximum concentration
of specified impurities are stated. The actual concentration
can be less.
• Purity classification is expressed as a quality code e.g.
5.5, where the number before the point represents the
number of nines and the last number indicates the last
decimal: 5.5 = 99.9995%, and 6.0 = 99.9999%. The given
percentage value represents the defined minimum
purity of actual gas. In the case of liquefied gas, the
purity always represents the vaporized liquid phase.
• Standard mixtures are delivered in molar units.
• R&D mixtures are specified by the customer and can be

Group green central gas supply system equipment for
inert and non-reactive gases used as carrier gas or
likewise, where gas integrity is non-crucial at cylinder
change.
Group blue central gas supply system equipment,
with own gas purge, for inert and non-reactive gases
and gas mixtures where gas integrity is important at
cylinder change.
Group orange central gas supply system equipment,
with purge gas (nitrogen or likewise) purging, for toxic
and reactive gases and gas mixtures, where gas integrity
and safety is important at cylinder change.
