Hydrogen use is typically riddled with safety concerns. In this presentation I highlight on- site Hydrogen gas generation as a safe and economical alternative to cylinder use for Gas Chromatography - FID detectors assuring constant, contact-free gas delivery to perform important and critical analytical testing.

Precision Hydrogen SL
Product overview - Webinar will start shortly

2. Introducing Precision SL

3. Streamline your GC with Precision SL by
Peak Scientific…Smaller, Simpler, Safer.
Positioning
The smallest and
easiest to use
hydrogen generator
for GC-FID.

4. Key proposition
Smallest laboratory-grade H2 gas generator for GC-FID on the
market. 1/5 of the size of existing 100 cc Precision H2 standard
Smaller
Designed to be uncomplicated and very easy to operate. H2 at
the push of a button with fast, simple user maintenance.
Simpler
Uncompromising safety with gas generated on-demand,
minimal storage and auto-shutdown safety features.
Safer
The most ergonomic and cost-effective alternative to H2
cylinders for GC detector gas, Peak quality at a lower cost.
Streamlined

5. § 100cc H2 up to 4 GC-FID
§ 99.9995% purity @ 100 psi (fixed)
§ One-button start-up and shutdown
§ Visual indication of desiccant
service interval
§ Easy end-user managed servicing
§ No maintenance costs in Y1
§ Auto-shutdown fail-safe feature
§ CE / RCM compliant
§ 2 year comprehensive warranty*
§ Available in black or white
Key Features
* Must change DI and Desiccant cartridge

6. Precision SL: Streamlined to be Smaller, Simpler and Safer
§ Single push-button operation + automatic system check
§ Fixed outlet pressure – GC managed pressure
§ AUS/ NZ: Auto water fill + bottle available
§ Fully end-user serviceable – no special tools required
§ Simple annual DI cartridge replacement
§ Quarterly desiccant capsule swap out
§ Proprietary sealed desiccant capsule with unique design
Changed in less than 60 seconds = zero down time!

7. Safety features
• Automatic system check on start-up
• Internal leak detection
• Over-pressure shutdown
• Capacity excess (external leak detection)
• <175cc gas volume within the Precision SL
200cc (no tanks)
• Meets IEC/ RCM standards for laboratory / AUS/
NZ use
• No compromise on safety (compared with
Precision H2)
• Portable (11 kg): No OHS issues of moving/
pushing cylinders (90 kg)
• No frequent gas truck deliveries = social
distancing and decreased carbon emissions
• No engineer visits required (2 years service parts
included in AUS/ NZ) = low cost of ownership +
social distancing.

8. FAQ - Safety
A 50L gas cylinder (90 kg)
contains around 9000 litres of
hydrogen
Therefore releasing 25% of the
contents would reach LEL
instantly.
A laboratory measuring 5m x 4m x
2.5m has a volume of 50m3, or
50,000 litres
The lower
explosive
level (LEL) of
H2 is 4.1%
Thus we need
2050 litres of H2
to reach the LEL
A SL H2 generator (11 kg)
producing 100 cc/min would
take 342 hours (ie 14 days) to
reach the LEL.
Assumes all fail safes fail and
a no escape of H2 gas in this
time.
We can’t have gas inside, how can a generator be safe in the lab?

9. FAQ
Can customers refill the desiccant cartridge?
No. the desiccant cartridges are single-use only and can only be
purchased from Peak or Peak Partners
How does the 2-year warranty work?
The generator must be registered with Peak and record the
replacement of the DI-cartridge within 13 months of installation. It
is that simple.
Can I use water from my tap?
No. Water quality must meet ASTM type II (<1µS conductivity / >1MΩ
resistivity) for all water filling options. Ask Peak if unsure.

10. FAQ
How long will the AWF operate for between fills?
The water tank should hold enough water to provide hydrogen gas for 1
week on the 100cc and the 4 L water bottle provides for 1 month of use.
Is it ok to supply the GC with 100psi pressure for the FID?
100psi does not exceed the recommended incoming gas pressure for
any major GC manufacturer’s instrument. The GC will regulate the
hydrogen pressure to meet the requirement of the detector.
How many DI columns and desiccant capsules are included with a new unit?
The 100cc model will ship with 1x DI cartridge and 2x desiccant
capsules. In AUS and NZ we will provide you with the 2nd year PM kit to
assure you obtain your 2 year warranty.
