Exhibit 1 Word Equations and Calculations for Varian 3800 (V) versus TRACE GC (I) Value Elements 1. Maintenance cost savings per yearVI = maintenance costsV - maintenance costsI

= €2,800.00 - €3,600.00 = - €800.00 2. Septum cost savings per yearVI = (number of septum changes per year x septum

price)V - (number of septum changes per year x septum price)I number of septum changes per year = operating minutes per year /(septum life time + septum change time) operating minutes per year = [(total hours per day x 60 minutes per hour) - maintenance downtime per day] x operating days per year operating minutes per yearV = [(24 hours per day x 60 minutes) - 50 minutes per day] x 240 days = 333,600 operating minutes per yearI = [(24 hours per day x 60 minutes) - 60 minutes per day] x 240 days = 331,200 Assumption: Contract labs are operating all three shifts, or 24 hours per day. septum life time in minutes = number of jobs per septum life time x job time in minutes job time in minutes = analysis time in minutes + cooling time in minutes job time in minutesV = 6.2 + 3.8 = 10 minutes job time in minutesI = 3.2 + 2.8 = 6 minutes septum life time in minutesV = 200 x 10 = 2000 minutes septum life time in minutesI = 1500 x 6 = 9000 minutes septum change time in minutes recalibration time in minutes

=

septum replacement time in minutes +

septum change time in minutesV = 3 + 10 = 13 minutes septum change time in minutesI = 3 + 6 = 9 minutes number of septum changes per yearV = 333,600 minutes per year /(2000 minutes + 13 minutes) = 165 septum changes per year

number of septum changes per yearI = 331,200 minutes per year /(9000 minutes + 9 minutes) = 36 septum changes per year Septum cost savings per yearVI = (number of septum changes per year x septum price)V - (septum price x number of septum changes per year)I = (165 x €2.00)V - (36 x €1.50)I = €330.00 - €54.00 = €276.00 3. Incremental profits per year through additional jobsIV = incremental jobs per yearIV x profit per job incremental jobs per yearIV = total jobs per yearI - total jobs per yearV total jobs per year = operating minutes per year / [job time in minutes + (septum change time in minutes / number of jobs per septum change)] total jobs per yearV = 333,600 / [10 minutes + (13 minutes / 200 jobs)] = 333,600 / 10.065 = 33,145 jobs per year total jobs per yearI = 331,200 / [6 minutes + (9 minutes / 1500 jobs)] = 331,200 / 6.006 = 55,145 jobs per year incremental jobs per yearIV = 55,145 jobs - 33,145 jobs = 22,000 jobs Incremental profits per year through additional jobsIV = (incremental jobs per yearIV) x profit per job = 22,000 jobs x €3.00 per job = €66,000 per year Placeholder 1. Septum change labor savings per yearVI = [(number of septum changes per year x septum change time in minutes)V (number of septum changes per year x septum change time in minutes)] I ÷ 60 minutes per hour x labor cost per hour = [(165 x 13) - (36 x 9)] ÷ 60 x €45.00 per hour = (2145 - 324) ÷ 60 x €45.00 = €1,365.75 One-Day Emergency Response Repair Service Guarantee Value of one-day response guarantee per incident = Profits per day - Price paid for faster service

1. Profits per day = number of jobs per day x profit per job

number of jobs per day = number of jobs per yearI / operating days per year = 55,145 jobs per year / 240 operating days per year =229 jobs per day Assumption: Round down 229.77 to the nearest complete job to be conservative. Profits per day = number of jobs per day x profit per job = 229 x €3.00 = €687.00 2. Price paid for faster service = average hours per incident x billing rate per hour = €125.00 x 3 hours = €375.00 Value of one-day response guarantee per incident = €687.00 - €375.00 = €312.00

Exhibit 2 Net Present Value Calculation for Interscience Trace GC versus Varian 3800 Total value-in-use per year (VIU) of Interscience TRACE GC (I) versus Varian 3800 (V): Differential value per yearIV = (Cost savings per year + Benefits per year)IV = - €524.00 + €66,000.00 = €65,476.00 Lifetime of Products = 5 years Differential Price per YearIV = (PriceI - PriceV) / Lifetime of products = (€45,000.00 - €40,000.00) / 5 = €1,000.00 Total VIU per YearIV = (ValueI - ValueV) + (PriceV - PriceI) = Differential valueIV + Differential priceIV = €65,476.00 - €1,000.00 = €64,476.00 Net present value of value-in-use (NPV VIU) Interscience TRACE GC and Varian 3800: Differential value per yearIV (V) = €65,476.00 Differential Price (P) = PriceI - PriceV = €45,000.00 - €40,000.00 = €5,000.00 Lifetimes of Products (N) = 5 years Initial Year (t) = 1 Customer Cost of Capital (k) = 10% N

NPV VIU = ∑[Vt/(1+k)t] - P = €248,206.00 - €5,000.00 = €243,206.00 t=1
